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.

Funny Car Horsepower claims vary widely—from 6,978 to 8,897—but are probably around 8,000 HP. Supercharged, nitromethane-fueled motors of this type also have a very high torque, which is estimated at about 7,000 ft⋅lbf (9,500 N⋅m). They routinely achieve a 6G acceleration from a standing start.
Honda Civic The eighth generation was released in September 2005, for the 2006 model year. For the eighth generation, Honda split the model into two different platforms, one for sedan and coupe, and one for a hatchback designed primarily for the European market using a simpler rear suspension from the Honda Fit and more aggressive styling. As of 2006, a total of 16.5 million Civics had been sold worldwide, with 7.3 million of them in the United States.[11] Although the North American and the home market model differ externally, they are mechanically identical. The hatchback is available as a three and five-door. Both Si and Type R trim levels continued although the Japanese and European Type R, while sharing the same engine size, are mechanically different. In the US, an improved, sportier version of the Civic Si 4-door tuned by tuner Mugen was offered, featuring cosmetic alterations and changes to the suspension, wheels, slight exterior differences, and exhaust system. A Canadian only Acura model received a new nameplate, changing from the Acura EL to the Acura CSX. The end of this model generation also marked a hiatus of the Civic Type R in Japan, with no successor model until the later tenth generation, going on sale mid-2017[12].
