Direct gas injection, despite the apparent advantages, poses critical challenges in obtaining adequate control of air-fuel mixture
quality when a NG DI combustion system is to be designed, mainly as a result of the fuel being constantly in gaseous state with low mass density [10,11,12].
The O2 sensor monitors the gases emitted by the vehicle engine thereby maintaining the appropriate air-fuel mixture
to facilitate efficient functioning of the engine in accordance to the emission regulatory norms.
At the level D feedback corrects air-fuel mixture
composition by analyzing the oxygen content in the purified EG to ensure effective cleaning.
Helical ramp' to induce ultra-high speed vortex of air-fuel mixture
in auxiliary combustion chamber
Infiniti's engine neatly sidesteps the problem of 'knocking', a process of inefficiency which can occur in higher compression ratio engines when the air-fuel mixture
combusts prematurely in the cylinder, potentially resulting in damage to the engine.
In addition, fuels with higher ratings are a few percentage points denser, which allows more power per litre in the vehicle," Mathai explained, adding that engine experts are of the view that using a low octane fuel when your car requires a higher version is just as damaging and will lead to an abnormal combustion of the air-fuel mixture
in the cylinder.
This is due to the higher oxygen content in the air-fuel mixture
enhances the oxidation of unburned hydrocarbons.
The automotive spark plug is a device designed to fit in each cylinder of a gasoline-powered internal-combustion engine to produce the electric spark for ignition of the air-fuel mixture
What is more, in case of alkylate petrol, a bigger amount of fuel (E100) has distilled at 100 [degrees]C, which leads to the assumption that in case of alkylate petrol, the evaporation of the air-fuel mixture
happens at lower temperatures, the engine warms more quickly and runs more stably.
The parts are used in a sensor kit that measures the inlet pressure of the air-fuel mixture
in each cylinder of a passenger car engine.
The smell of rotten eggs could indicate a plugged or damaged catalytic converter or an air-fuel mixture
with not enough air.
The ratio of precompression volume to postcompression volume for an air-fuel mixture
stands at 14.
