Engine Architecture
The Accord Crosstour's engine is a sophisticated 3.5-liter, SOHC, 24-valve, 60-degree, V-6, aluminum-block-and-head design that is compact, Auto Specials light-weight and powerful. The i-VTEC valvetrain and high efficiency consumption manifold optimize cylinder-filling effectivity across a wide range of engine speeds. Low-restriction consumption and exhaust programs, a 10.5:1 compression ratio and curler-type rocker arms further support efficiency and energy supply across a broad RPM range.

The Accord Crosstour's V-6 has a die-solid lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin casting course of, the skinny-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with 4 bolts per bearing cap for inflexible crankshaft help and minimized noise and vibration. Both the block and caps are warmth handled for larger strength.

A solid metal crankshaft is used for optimum power, rigidity and sturdiness with minimal weight. Instead of heavier nuts and bolts, connecting rod caps are secured in place with smaller, high-tensile-strength fasteners that screw straight into the connecting rod. Short-skirt, solid-aluminum, flat-high pistons are notched for valve clearance and fitted with full-floating piston pins.

Like other Honda V-6 powerplants, the Accord Crosstour V-6 cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft through an automatically tensioned toothed belt. Product of low-stress cast, low-porosity aluminum, each cylinder head incorporates an built-in exhaust manifold to reduce elements rely, enhance flow and optimize the situation of the shut-coupled catalyst on every cylinder bank.

The cylinder head employs 4-valve combustion chambers, the very best method to optimum performance with wonderful gasoline Schedule Service efficiency and really low emissions. Valves are clustered close to the middle of the bore to attenuate combustion chamber quantity and to supply ample squish area. The 10.5:1 compression ratio helps maximize thermal efficiency, energy output and fuel efficiency. One centrally located camshaft per cylinder financial institution is pushed by a fiberglass-bolstered toothed belt. Head gaskets are made from excessive-energy supplies to contain combustion pressures.

i-VTEC with three-stage Variable Cylinder Administration™ (VCM™)
To help enhance the gas effectivity of the V-6 engine, it incorporates the newest generation of Honda's VCM, which expands the operational range of cylinder activation compared to the Accord Sedan and Coupe V-6 engine. The Accord Crosstour's VCM system can operate on three, 4 or all six cylinders, and is commonplace on each two-wheel-drive and 4-wheel-drive models.

During startup, acceleration or when climbing hills - any time excessive energy output is required - the engine operates on all six cylinders. Throughout reasonable pace cruising and at low engine hundreds, the system operates only one Order Parts bank of three cylinders. For reasonable acceleration, higher-pace cruising and mild hills, the engine operates on four cylinders.

With three operating modes, the VCM system can finely tailor the working displacement of the engine to match the driving requirements from moment to moment. Since the system routinely closes each the consumption and exhaust valves of the cylinders that aren't used, pumping losses associated with intake and exhaust are eradicated and gasoline efficiency increases. The VCM system combines maximum performance and maximum gasoline effectivity - two characteristics that do not usually coexist in standard engines.

VCM deactivates specific cylinders through the use of the VTEC (Variable Valve-Timing and Lift Digital Management) system to close the consumption and exhaust valves whereas concurrently the Powertrain Control Module cuts fuel to these cylinders. When working on three cylinders, the rear cylinder financial institution is shut down. When operating on four cylinders, the left and heart cylinders of the front bank operate, and the suitable and heart cylinders of the rear bank operate.

The spark plugs proceed to fireplace in inactive cylinders to attenuate plug temperature loss and forestall fouling induced from incomplete combustion during cylinder re-activation. The system is electronically controlled, and makes use of particular integrated spool valves that do double duty as rocker-shaft holders in the cylinder heads. Primarily based on instructions from the system's electronic control unit, the spool valves selectively direct oil stress to the rocker arms for particular cylinders. This oil strain in flip drives synchronizing pistons that connect and disconnect the rocker arms.

The VCM system screens throttle position, vehicle velocity, engine velocity, automatic-transmission gear choice and other factors to find out the right Auto Finance cylinder activation scheme for the operating conditions. In addition, the system determines whether engine oil strain is appropriate for VCM switching and whether catalytic-converter temperature will remain within the proper range. To smooth the transition between activating or deactivating cylinders, the system adjusts ignition timing, drive-by-wire throttle position and turns the torque converter lock-up on and off. Because of this, the transition between three-, 4-, and 6-cylinder operation is unnoticeable to the driver.

High-Move Exhaust System with Twin Outlets
A low-restriction, high-output, exhaust system is crucial to efficient power and torque production. A very new exhaust system on the Accord accommodates its increased energy output. Tubing diameter has been increased and new twin silencers are used. High-chromium chrome steel is used all through the exhaust system for excellent durability. The Accord Crosstour's exhaust system is customized primarily based on whether the automobile is front-wheel-drive or four-wheel-drive. The front-wheel-drive exhaust system utilizes one massive and one small resonator previous to the splitter that goes to every muffler. For packaging issues with the propeller shaft and fuel tank on 4-wheel drive models, two smaller resonators are placed after the splitter that divides the exhaust route to every rear muffler. Both exhaust techniques achieve the identical flow rate of one hundred thirty five l/s.

Key contributors to the engine's low emissions performance are its excessive-effectivity catalytic converters. The engine has its exhaust manifolds cast straight into the aluminum alloy cylinder heads to scale back weight and place every major catalytic converter as close as potential to the combustion chambers. Excessive-efficiency close-coupled converters mount directly to the exhaust port of each cylinder head for terribly speedy converter activation after engine startup. A third converter is positioned shortly downstream, beneath the passenger compartment floor. Each converters use a thin-wall design that increases internal reaction area and improves efficiency.

Powertrain Control Unit (PCU)
A 32-bit, 96MHz powertrain control unit (PCU) inside the powertrain control module calculates injection timing and length after assessing an array of sensor indicators: crankshaft and camshaft place, throttle place, coolant temperature, intake manifold stress and temperature, atmospheric strain and exhaust-fuel oxygen content. The PCU controls the Programmed Fuel Injection (PGM-FI) and that i-VTEC valvetrain and also communicates with processors that regulate the five-pace computerized transmission.

Drive-By-Wire (DBW) Throttle System™
The Accord Crosstour's drive-by-wire throttle system makes use of good electronics instead of a conventional cable system to attach the throttle pedal to the throttle butterfly in the intake tract. Apart from permitting engineers to program the connection between throttle pedal movement and engine response, the system optimizes engine response to suit driving conditions. The system monitors throttle pedal place, throttle butterfly position, automobile velocity, engine pace and engine vacuum. This information is used to outline the throttle management sensitivity.

Programmed Gasoline Injection (PGM-FI)
The Accord Crosstour's PGM-FI regularly adjusts the gas delivery to yield the best mixture of energy, low gasoline consumption and low emissions. A number of sensors constantly monitor Blog essential working parameters, comparable to throttle position, consumption air temperature, coolant temperature, ambient air pressure, intake airflow quantity, intake manifold stress, exhaust air-gasoline ratio and the place of the crankshaft and cams.

Direct Ignition and Detonation/Knock Management
The Powertrain Control Unit (PCU) displays engine features to find out one of the best spark timing. An engine-block mounted acoustic detonation/knock sensor "listens" to the engine, and based mostly on this enter, the PCU retards the ignition timing to prevent doubtlessly damaging detonation. An ignition coil unit for every cylinder is positioned above every spark plug's access bore.

Regular Unleaded Gasoline
To maintain working prices at a minimum, all Accord fashions are designed to use comparatively much less-costly common unleaded gasoline, because of compact four-valve combustion chambers and precise Contact Us fuel injection and spark control.

Upkeep Minder System and Tune-Up Intervals
The Accord Crosstour's Maintenance Minder system calculates the engine's tune-up schedule based on driving circumstances (tracked by the PCU). When figuring out proper maintenance intervals, the system minimizes proprietor guesswork about whether or not the car is being operated in normal or severe conditions. The Accord Crosstour's Upkeep Minder data seems within the odometer show, and signifies when to alter the oil, oil filter (every other oil change), air cleaner, transmission fluid, spark plugs, coolant, Actual Time 4WD differential fluid as well as when to rotate the tires. A tune-up will not be required till about one hundred,000 miles. (100K+/- Miles No Scheduled Tune-ups could differ with driving conditions. Doesn't apply to fluid and filter changes. Actual mileage is decided by precise driving conditions. The owner's handbook comprises full particulars). Lengthy-life fluids have been used for reduced maintenance costs and environmental impression (fluid disposal). As a result, engine coolant adjustments are wanted about every 10 years or approximately one hundred,000 miles, and engine oil adjustments are required round 7,500 miles under regular driving conditions, or yearly if fewer miles are driven per year. The maintenance minder system calculates the exact miles between service intervals.

5-Pace Automated Transmission with Grade Logic Management
The Accord Crosstour's 5-speed computerized transmission has several options engineered specifically to match its efficiency necessities, including further-wide gear ratios for good low-finish response and comfortable freeway cruising; a computer-managed lock-up torque converter; a inflexible alloy case; and a 4-shaft design. Honda Grade Logic Management know-how is designed to carry the car in a decrease gear when climbing or descending a steep grade for improved performance.

The transmission options an expanded complement of sensible logic controls. A pc-managed lock-up torque converter is offered to maximise gas efficiency. Torque-converter lock-up and shift timing are each managed by a CPU working in cooperation with the engine's central processing unit. An over-operating clutch is provided for first gear to smooth upshift quality. A direct-control strategy is used to provide actual-time strain management of the transmission's clutches. Varied management strategies unique to the Accord Crosstour are utilized to permit for easy coordination of engine and transmission operations. For example, the driveline shock that usually accompanies gear changes is minimized by momentarily reducing engine torque throughout shifting.

To reduce gear "looking" and unnecessary shifting, Grade Logic Control and Shift Maintain Management programs are integrated into the shift programming of Accord automated transmissions. Grade Logic Management alters the 5-speed automatic's shift schedule, decreasing shift frequency whereas touring uphill or downhill. Using inputs monitoring throttle place, car pace and acceleration/deceleration, Grade Logic compares the working parameters with a digital map saved within the transmission computer. When the system determines the Accord is on a hill, the shift schedule is adjusted to robotically maintain the transmission in a lower gear for better climbing power or elevated downhill engine braking.
