They dont, diesel engines are generally more reliable than gas engines, and alot simpler due to the fact that the entire ignition system found in gas-powered engines is deleted entirely from the diesel equation. (Diesel engines don't have spark plugs, they rely on compression to ignite the fuel, meaning: they sqeeze the diesel fuel so much that it explodes)
Diesel engines have more torque especially at low rpms. This gives them much more pulling power. They also last much longer that gasoline engines. require less maintenance, and get better fuel economy.
Electric and diesel engines are generally more efficient and environmentally friendly compared to steam engines. They require less maintenance, have quicker startup times, and produce less pollution, making them more suitable for modern transportation needs. Additionally, electric engines offer instant torque and higher energy efficiency, while diesel engines provide greater range and power for heavy-duty applications. Overall, the advancements in technology have made electric and diesel engines more reliable and cost-effective than traditional steam engines.
The steam engine has largely been replaced by diesel engines due to their greater efficiency, lower operational costs, and ease of use. Diesel engines require less maintenance, can be operated more flexibly, and provide better fuel economy compared to steam engines, which rely on water and require significant time and resources to generate steam. Additionally, diesel engines offer higher power-to-weight ratios, making them more suitable for modern transportation needs. As a result, diesel technology has become the preferred choice for many applications in rail, road, and marine transportation.
More torque, less maintenance, longer engine life, and uses less fuel.
The diesel engine is generally more powerful than a steam engine, primarily due to its higher thermal efficiency and ability to generate greater torque. Diesel engines can deliver more power in a smaller and lighter package, making them suitable for a wide range of applications, from vehicles to heavy machinery. While steam engines can produce significant power, they are often less efficient and require more maintenance due to their complexity and reliance on water and fuel sources. Overall, diesel engines are more versatile and powerful for modern use.
Batteries are basically the same for petrol or deisel engines, but diesel engines require more cranking force and demand a bigger battery. So a battery from a diesel engine is ok for petrol, providing it fits.
Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.
Diesel tractors are superior to gas tractors because diesel engines have fewer maintenance issues and produce more useful energy.
Diesel engines are more efficient than gasoline engines.
diesel engines doesn't use spark plug but uses heater plug.petrol engines produces more torque than petrol engines but petrol engines produces more acceleration than diesel engines.petrol engine is faster to be heated than diesel engine.
Normally Diesel engines produce more torque than gasoline engines but less horsepower. Gasoline engines rev up quicker and produce higher horsepower at higher rpms. Diesel engines develop their higher torque at lower rpms which allows a diesel to carry a heavier load.
Diesel engines have such a high engine compression ratio, they require a more powerful starter, which in turn requires more battery power. That is why diesels have two batteries.
