When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft) that pulls gases out of the crankcase. To prevent too much vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. [1] The breather is often located in the oil cap.
A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
Compressed air cars are emission free. They also do not require a connection to the electric grid. A wind turbine or other renewable energy source can directly drive an air compressor or hydraulic pump. Compressed air cars do not rely on petrol stations or an electric grid. While centralized infrastructure might not be needed, it is an option.
With the advent of advanced emission controls and more advanced fuel injection methods, modern vehicles do not have a thermostatic air intake system and the factory-installed air intake draws unregulated cold air. Aftermarket cold air intake systems are marketed with claims of increased engine efficiency and performance. The putative principle ...
A cold start is an attempt to start a vehicle's engine when ambient temperatures are much lower than its normal operating temperature. [1] A cold start can be difficult for an engine due to higher viscosity of oil and fuel in cold temperatures.
Also gas pedal. A throttle in the form of a foot-operated pedal, or sometimes a hand-operated lever or paddle, by which the flow of fuel to the engine (and thereby the engine speed) is controlled, with depression of the pedal causing the vehicle to accelerate. admission stroke See induction stroke. aftermarket air brake 1. A type of brake in which the force that actuates the brake mechanism is ...

Air injection is now used to support the catalytic converter's oxidation reaction, and to reduce emissions when an engine is started from cold. After a cold start, an engine needs an air-fuel mixture richer than what it needs at operating temperature , and the catalytic converter does not function efficiently until it has reached its own ...
