Common clearances between moving parts of an engine can be best compared to the space between the teeth of a gear. Just as the teeth need sufficient space to rotate freely without binding, engine components require precise clearances to allow for smooth movement, prevent wear, and ensure efficient operation. Proper clearance is essential to accommodate thermal expansion and lubrication, much like how gear teeth must align properly to avoid mechanical failure.

A four-stroke engine runs cooler than a two-stroke engine primarily because it has a more efficient cooling system due to its longer cycle, which allows for more complete combustion and better heat dissipation. In a four-stroke engine, the intake, compression, power, and exhaust strokes are separated, giving more time for heat to escape during the exhaust stroke. In contrast, a two-stroke engine fires once every revolution, leading to less time for heat to dissipate and often resulting in higher operating temperatures. Additionally, two-stroke engines typically mix oil with fuel for lubrication, which can also contribute to increased heat generation.

High fuel consumption in an Isuzu Wizard diesel engine can be attributed to several factors, including poor engine tuning, clogged fuel filters, or malfunctioning injectors.
