What does dual-fuel engine mean

Dual-fuel vehicle refers to a vehicle equipped with two sets of fuel supply systems. One set supplies natural gas or liquefied petroleum gas, and the other set supplies fuels other than natural gas or liquefied petroleum gas. Two sets of fuel supply systems supply fuel to the cylinder according to the preset proportion.

It belongs to a kind of fuel-powered car [gas fuel-powered automobile], which uses flammable gases to make energy-driven cars.

Gasoline/natural gas dual-use fuel engine is an engine that is suitable for both gasoline and natural gas. However, after the gasoline engine was modified into a gasoline/CNG dual-fuel engine, the power and torque of the engine decreased significantly when natural gas was used.

Gasoline dual-fuel green environmentally friendly cars were born. Due to the high calorific value, strong explosion resistance, wide range of combustible concentration, high critical temperature, and can greatly reduce the harmful components after engine emissions, it is becoming more and more popular.

What are car engines divided according to the fuel used?

According to the classification of fuel used, it can be divided into gasoline engines, diesel engines and engines that use substitute fuels methanol, ethanol and liquefied petroleum gas. Engines fueled by gasoline are called gasoline engines, engines fueled by diesel are called diesel engines, and engines fueled by liquefied gas are called liquefied gas engines.

There are two types: gasoline and diesel. The function of the car engine is to provide power to the car, which is very important to the car, equivalent to the existence of the heart. The engines generally used in gasoline include gasoline engines and diesel engines, both of which belong to the resurrected internal combustion engines, which can convert the chemical energy of fuel into mechanical energy.

[Autohome Encyclopedia] The fuel forms of Autohome engines are divided into: gasoline, diesel, oil-electric hybrid, pure electric, plug-in hybrid, additional program and fuel cells, etc.

At present, the fuels of automobile engines are divided into: gasoline, diesel, natural gas, methanol. Traditional names: gasoline, diesel, dual fuel. According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle electric motors and hybrid power, etc.

According to the working mode of the air intake system, it can be divided into four types: natural intake, turbocharging, mechanical supercharging and double supercharging. According to the piston movement mode, it can be divided into two types: resurrected internal combustion engine and rotary piston engine. According to the cylinder arrangement, it is divided into in-line engine, V-type engine, W-type engine and horizontally opposed engine, etc.

Classification of gas-fuel engines?

1. Classification according to different fuels. Gasoline engine: gasoline is used as fuel, which is mainly used for cars, motorcycles and other vehicles. Diesel engine: diesel is used as fuel, which is mainly used for trucks, construction machinery and other heavy vehicles.

2. [Classification of engines] Classified according to the piston movement mode: piston internal combustion engines can be divided into two types: resurrection plug type and rotary piston type.The former piston makes a reciprocating linear motion in the cylinder, while the latter piston rotates in the cylinder.

3. Gas fuel mainly includes natural gas, liquefied petroleum gas and other fuels. Classified according to the number of strokes: it can be divided into four-stroke and two-stroke engines.

4. The so-called gas fuel engine refers to natural gas engines, compressed natural gas engines and liquefied petroleum gas engines, which are generally modified with gasoline engines or diesel engines. In many cases, two types of fuels can be used at the same time. According to the different cooling methods, it can be divided into water-cooled and air-cooled.

5. Internal combustion engines are classified according to the fuel used. According to the different fuels used, they can be divided into gasoline engines, diesel engines and gas fuel engines. Internal combustion engines that use gasoline as fuel are called gasoline engines;Internal combustion engines that use diesel as fuel are called diesel engines. Gas fuels mainly include natural gas, liquefied petroleum gas and other fuels.
