Engine Architecture
The Accord Crosstour's engine is an advanced 3.5-liter, SOHC, 24-valve, 60-diploma, V-6, aluminum-block-and-head design that's compact, Auto Specials lightweight and powerful. The i-VTEC valvetrain and high effectivity intake manifold optimize cylinder-filling effectivity throughout a variety of engine speeds. Low-restriction intake and exhaust systems, a 10.5:1 compression ratio and curler-kind rocker arms additional aid effectivity and energy delivery across a broad RPM range.

The Accord Crosstour's V-6 has a die-forged light-weight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin casting process, the skinny-wall liners are high in energy and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. Both the block and caps are warmth handled for better strength.

A solid steel crankshaft is used for max energy, rigidity and durability with minimum weight. As an alternative of heavier nuts and bolts, connecting rod caps are secured in place with smaller, excessive-tensile-strength fasteners that screw directly into the connecting rod. Brief-skirt, cast-aluminum, flat-top 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 solid, low-porosity aluminum, every cylinder head incorporates an integrated exhaust manifold to cut back components count, improve stream and optimize the location of the shut-coupled catalyst on every cylinder bank.

The cylinder head employs 4-valve combustion chambers, the best approach to optimum efficiency with glorious gasoline Schedule Service effectivity and really low emissions. Valves are clustered close to the center of the bore to attenuate combustion chamber quantity and to offer ample squish area. The 10.5:1 compression ratio helps maximize thermal efficiency, energy output and gasoline efficiency. One centrally positioned camshaft per cylinder financial institution is driven by a fiberglass-strengthened toothed belt. Head gaskets are fabricated from excessive-strength supplies to contain combustion pressures.

i-VTEC with 3-stage Variable Cylinder Administration™ (VCM™)
To assist enhance the gas efficiency of the V-6 engine, it incorporates the latest 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, four or all six cylinders, and is normal on both 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. During reasonable speed cruising and at low engine masses, the system operates just one Order Parts financial institution of three cylinders. For average acceleration, greater-speed cruising and mild hills, the engine operates on 4 cylinders.

With three working modes, the VCM system can finely tailor the working displacement of the engine to match the driving necessities from moment to moment. Because the system mechanically closes each the intake and exhaust valves of the cylinders that are not used, pumping losses associated with consumption and exhaust are eliminated and gas effectivity increases. The VCM system combines most performance and maximum gasoline efficiency - two traits that don't usually coexist in standard engines.

VCM deactivates specific cylinders through the use of the VTEC (Variable Valve-Timing and Raise Electronic Control) system to shut the intake and exhaust valves while simultaneously the Powertrain Control Module cuts gas to these cylinders. When operating on three cylinders, the rear cylinder financial institution is shut down. When working on four cylinders, the left and heart cylinders of the entrance bank function, and the suitable and middle cylinders of the rear financial institution operate.

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

The VCM system displays throttle position, vehicle speed, engine pace, computerized-transmission gear choice and different components to determine the correct Auto Finance cylinder activation scheme for the working conditions. In addition, the system determines whether engine oil pressure is suitable for VCM switching and whether or not catalytic-converter temperature will stay in the correct range. To smooth the transition between activating or deactivating cylinders, the system adjusts ignition timing, drive-by-wire throttle place and turns the torque converter lock-up on and off. Consequently, the transition between three-, four-, and six-cylinder operation is unnoticeable to the driver.

Active Management Engine Mounts (ACM)

High-Circulate Exhaust System with Dual Shops
A low-restriction, excessive-output, exhaust system is crucial to environment friendly power and torque production. A totally new exhaust system on the Accord accommodates its increased energy output. Tubing diameter has been elevated and new twin silencers are used. High-chromium chrome steel is used all through the exhaust system for wonderful durability. The Accord Crosstour's exhaust system is customized based on whether or not the automobile is entrance-wheel-drive or 4-wheel-drive. The front-wheel-drive exhaust system makes use of one massive and one small resonator prior to the splitter that goes to every muffler. For packaging considerations with the propeller shaft and fuel tank on four-wheel drive fashions, two smaller resonators are positioned after the splitter that divides the exhaust route to every rear muffler. Each exhaust systems achieve the identical circulate charge of 135 l/s.

Key contributors to the engine's low emissions performance are its excessive-effectivity catalytic converters. The engine has its exhaust manifolds solid immediately into the aluminum alloy cylinder heads to cut back weight and position every major catalytic converter as close as doable to the combustion chambers. High-effectivity close-coupled converters mount directly to the exhaust port of each cylinder head for extremely rapid converter activation after engine startup. A third converter is positioned shortly downstream, beneath the passenger compartment floor. Each converters use a skinny-wall design that increases internal reaction space and improves efficiency.

Powertrain Control Unit (PCU)
A 32-bit, 96MHz powertrain management unit (PCU) throughout the powertrain management module calculates injection timing and duration after assessing an array of sensor alerts: crankshaft and camshaft place, throttle place, coolant temperature, consumption manifold strain and temperature, atmospheric pressure and exhaust-gas oxygen content. The PCU controls the Programmed Gas Injection (PGM-FI) and i-VTEC valvetrain and in addition communicates with processors that regulate the five-velocity automated transmission.

Drive-By-Wire (DBW) Throttle System™
The Accord Crosstour's drive-by-wire throttle system makes use of good electronics as a substitute of a standard cable system to connect the throttle pedal to the throttle butterfly within the consumption tract. Besides permitting engineers to program the connection between throttle pedal motion and engine response, the system optimizes engine response to suit driving conditions. The system monitors throttle pedal position, throttle butterfly place, vehicle speed, engine speed and engine vacuum. This info is used to define the throttle management sensitivity.

Programmed Gas Injection (PGM-FI)
The Accord Crosstour's PGM-FI continually adjusts the gasoline delivery to yield the very best mixture of energy, low gasoline consumption and low emissions. A number of sensors consistently monitor Blog essential operating parameters, comparable to throttle position, intake air temperature, coolant temperature, ambient air stress, consumption airflow volume, intake manifold stress, exhaust air-fuel ratio and the position of the crankshaft and cams.

Direct Ignition and Detonation/Knock Management
The Powertrain Management Unit (PCU) screens engine functions to find out the most effective spark timing. An engine-block mounted acoustic detonation/knock sensor "listens" to the engine, and based mostly on this input, the PCU retards the ignition timing to prevent probably damaging detonation. An ignition coil unit for each cylinder is positioned above every spark plug's access bore.

Common Unleaded Gasoline
To keep working prices at a minimal, all Accord fashions are designed to make use of relatively less-costly common unleaded fuel, because of compact 4-valve combustion chambers and precise Contact Us gas injection and spark control.

Upkeep Minder System and Tune-Up Intervals
The Accord Crosstour's Upkeep Minder system calculates the engine's tune-up schedule based mostly on driving situations (tracked by the PCU). When determining proper upkeep intervals, the system minimizes proprietor guesswork about whether the car is being operated in customary or extreme conditions. The Accord Crosstour's Upkeep Minder information appears within the odometer display, and signifies when to change the oil, oil filter (each different oil change), air cleaner, transmission fluid, spark plugs, coolant, Real Time 4WD differential fluid in addition to when to rotate the tires. A tune-up is just not required until about a hundred,000 miles. (100K+/- Miles No Scheduled Tune-ups could range with driving conditions. Doesn't apply to fluid and filter changes. Precise mileage is determined by actual driving conditions. The proprietor's manual contains full particulars). Long-life fluids have been used for lowered maintenance costs and environmental impact (fluid disposal). Because of this, engine coolant modifications are wanted about each 10 years or roughly 100,000 miles, and engine oil adjustments are required around 7,500 miles under regular driving circumstances, or annually if fewer miles are pushed per year. The maintenance minder system calculates the exact miles between service intervals.

5-Pace Automatic Transmission with Grade Logic Control
The Accord Crosstour's 5-velocity automated transmission has several features engineered specifically to match its performance necessities, together with further-wide gear ratios for good low-finish response and comfortable freeway cruising; a pc-controlled lock-up torque converter; a rigid alloy case; and a four-shaft design. Honda Grade Logic Management technology is designed to hold the car in a decrease gear when climbing or descending a steep grade for improved performance.

The transmission options an expanded complement of smart logic controls. A computer-controlled lock-up torque converter is offered to maximise gasoline 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-working clutch is supplied for first gear to smooth upshift quality. A direct-control technique is used to offer actual-time stress management of the transmission's clutches. Various management strategies exclusive to the Accord Crosstour are utilized to permit for easy coordination of engine and transmission operations. For instance, the driveline shock that usually accompanies gear changes is minimized by momentarily reducing engine torque during shifting.
