Diesel Generators Use A Relatively Non-flammable Fuel, Making It Safer To Store

Diesel generators are considered to be more fuel efficient and cost-effective in the long run, as its fuel lasts longer than in petrol generators. A diesel generator can run at low RPMs, but even with lower speeds, it can produce more torque, thus extending engine life while minimising operational noise. And because the generator uses diesel, it is considered safer in certain job sites where extreme flame and heat are involved.

Why are diesel engines non-flammable?

The diesel engine ignites through a compression process. Gasoline engines rely on spark ignition, while diesel engines draw air into the engine, subjecting it to high levels of compression heat to increase its temperature. When the pressure and temperature reach their peak, diesel that enters the engine can ignite. In gasoline engines, gas and air are introduced before the ignition. In a diesel engine, fuel and air are fused into the engine at various stages. Diesel is injected into the engine through an injector, unlike in gasoline engines where a carburettor is used. Gasoline engines also mix fuel and air together to enter the engine before being compressed, and in diesel engines, only the air is compressed.

Diesel fuel burns cleaner compared to gasoline, and it is less flammable, too. There are no spark plugs in diesel engines, so you can start the generator safely. Diesel generators are less likely to cause fires and explode than gas combustion engines. The diesel fuel itself does not evaporate quickly, making it appropriate for extended usage in the most demanding environments.

Newer diesel engines are engineered to be low cost, low maintenance, and quieter without compromising reliability. They are also cheaper to maintain because they do not have spark plugs and spark wires.
