Diesel engines use diesel fuel, which is heavier and oilier than gasoline. Diesel fuel contains hydrocarbons that are more complex and have higher energy density than gasoline.
Diesel engines operate on the diesel cycle, which is similar to the Otto cycle but lacks a spark plug. Instead, diesel engines compress air to a high temperature, causing the diesel fuel to ignite spontaneously when injected into the combustion chamber
Diesel engines are known for their high torque output, fuel efficiency, and durability. They are commonly used in heavy-duty vehicles such as trucks, buses, locomotives, ships, and construction equipment
Petrol
Petrol engines, also known as gasoline engines, are designed to run on gasoline, a petroleum-based fuel. Gasoline is a mixture of hydrocarbons derived from crude oil refining
Petrol engines operate on the Otto cycle, which consists of four strokes: intake, compression, power, and exhaust. These engines typically use a spark plug to ignite the air-fuel mixture in the combustion chamber
Also known for their smooth operation, quick acceleration, and relatively quiet operation compared to diesel engines. They are commonly used in passenger cars, motorcycles, and small aircraft
Kerosene
Kerosene engines, sometimes referred to as paraffin engines, use kerosene as their fuel source. Kerosene is a refined petroleum product similar to diesel fuel but with a lower ignition point.
Kerosene engines typically operate on a similar principle to diesel engines, with compression ignition. However, they are often designed to handle kerosene’s lower volatility and different combustion characteristics.
Kerosene engines are less common than petrol and diesel engines but are still used in certain applications, particularly in regions where kerosene is more readily available or as a backup power source. They may be found in some stationary generators, agricultural machinery, and industrial equipment.
