how many spark plugs in a honda civic hybrid
Honda Civic Hybrid The two spark plugs in each cylinder can fire either sequentially or simultaneously, enabling more efficient burning during lean-burn mode and more often lean-burn operation. The engine can operate at a lean 22:1 air-to-fuel ratio more than 60 percent of the time on a flat road. The VTEC cylinder idling system of the engine closes the valves in three of the four cylinders when the car is decelerating, reduces the power lost to the engine by 50 percent, and allows the IMA to extract more electrical energy during braking. The rocker arms operating the intake and exhaust valves have two modes: valve-lift mode or idle mode. They are engaged via a synchronizing piston. During deceleration, the synchro piston disengages the lift-mode rocker arm so that the valves remain at rest, effectively sealing off the cylinder.
Honda Civic (sixth generation) The CX, DX, VP, and LX trim packages used the SOHC 16v D16Y7 engine. It produced 106 hp (79 kW) at 6,200 RPM, 103 lb⋅ft (140 N⋅m) of torque at 4,600 RPM, with a compression ratio of 9.6:1. Fuel injection was multi-point.[11]
Classic car Cars 20 years and older typically fall into the classic class.
Catalytic converter As an alternative, catalytic converters were moved to a third of the way back from the engine, and were then placed underneath the vehicle.
Honda Super Cub In 2007, Honda began installing their PGM-FI fuel injection system for the Honda Cubs in the Japanese market for lower smog-forming emission.[37]
Ignition coil Where coils are individually applied per cylinder, they may all be contained in a single molded block with multiple high-tension terminals. This is commonly called a coil-pack.
