As a mechanical engineering expert with a focus on internal combustion engines, I can provide a detailed explanation about the fuel types used in 4-stroke engines.
The 4-stroke engine is a type of internal combustion engine that has a four-stroke cycle. This cycle includes four distinct phases: intake, compression, power, and exhaust. The 4-stroke engine is known for its efficiency and reliability, which is why it's widely used in various applications, including lawn mowers, cars, and motorcycles.
Fuel for 4-Stroke Engines:
1. Unleaded Petrol: The most common fuel for 4-stroke engines is unleaded petrol, also known as gasoline. This is a hydrocarbon fuel that is refined from crude oil. It is a clean-burning fuel that does not contain lead, which was once added to gasoline to improve engine performance but has since been phased out due to health and environmental concerns.
2. Ethanol Blends: Some 4-stroke engines can also run on ethanol blends. Ethanol is an alcohol-based fuel that can be mixed with gasoline to create a cleaner-burning fuel. E10, for example, is a blend of 10% ethanol and 90% gasoline. Ethanol is renewable and can be made from crops like corn and sugarcane.
3. Diesel: While diesel is typically associated with compression-ignition engines, some 4-stroke engines are designed to run on diesel fuel. These are less common and are usually found in larger, more industrial applications.
4. Alternative Fuels: With the push towards cleaner energy, there has been an increase in the development of alternative fuels for 4-stroke engines. These can include biofuels, hydrogen, and even electric power in the form of hybrid systems.
Advantages of 4-Stroke Engines:
- Efficiency: 4-stroke engines are more fuel-efficient than their 2-stroke counterparts due to their cycle design. They convert more of the fuel's energy into mechanical work.
- Reliability: The 4-stroke engine is known for its reliability. It has fewer moving parts and a longer stroke cycle, which can lead to a longer engine life.
- Emissions: Modern 4-stroke engines are designed to meet stringent emissions standards, making them more environmentally friendly than older models.
Maintenance Considerations:
- Fuel Quality: It's important to use high-quality fuel in 4-stroke engines. Poor-quality fuel can lead to carbon buildup and other issues that can damage the engine.
- Oil Changes: Regular oil changes are crucial for the longevity of a 4-stroke engine. The oil helps to lubricate the engine's moving parts and keep them running smoothly.
- Tune-Ups: Regular tune-ups, including spark plug changes and valve adjustments, can help maintain the performance and efficiency of a 4-stroke engine.
In conclusion, 4-stroke engines are versatile and can run on a variety of fuels, with unleaded petrol being the most common. They offer a balance of efficiency, reliability, and environmental responsibility, making them a popular choice for many applications.

There are two kinds of fuel run lawn mowers, they are 2 stroke mowers and 4 stroke mowers. 4 stroke mowers use just ordinary unleaded petrol. 2 stroke mowers use a mix of ordinary unleaded petrol and a special oil. You have to mix them together using the right ratio.Nov 2, 2008
