In a gasoline engine, it is a fuel-air mixture that is drawn in during the intake stroke, unless the engine is fuel injected. In a fuel injected or a diesel engine, it is air, because the fuel (gasoline or diesel) is injected at the "last moment" before ignition.

Describe the position of the intake valve and the exhaust valve during each stroke of a four stroke engine?

In a four-stroke engine, the intake valve opens in the intake stroke, allowing air-fuel mixture to enter, while the exhaust valve remains closed. During the compression stroke, both valves stay closed to build pressure. In the power stroke, the fuel ignites, pushing the piston down, with both valves still closed to retain pressure. Finally, in the exhaust stroke, the exhaust valve opens, allowing gases to escape, while the intake valve stays shut. This cycle repeats continuously, ensuring efficient engine operation.


Least number of valves required at the top of a four-stroke cycle engine?

Two. Intake, and exhaust.


How many camshaft revolution in stroke cycle engine?

In a typical four-stroke engine, the camshaft completes two revolutions for every one stroke cycle of the piston. This is because the four-stroke cycle consists of intake, compression, power, and exhaust strokes, which require the camshaft to operate the intake and exhaust valves twice during each cycle. Thus, for every complete cycle of the engine, the camshaft turns two full revolutions.


What is chalwyn valve used for?

Chalwyn valves can be attached to a diesel engine air intake system. The valve is designed to safely shutdown the engine in the event of external vapours or gasses being sucked into the engine through the air intake. In areas where there is a chance of vapour ignition a chalwyn valve will normally be specified by the site owner.
