The first electricity generating engines were diesel type. But with the advancement of technology, the electric motor has also evolved. Even the classic diesel electric engine, which was once polluting, noisy and smelly, has become one of today's ideal electric engines in the new structure. Gasoline and diesel electric motors are two types of these devices whose names have been heard a lot. The difference between diesel and gasoline electric motors is very evident in terms of structure and performance. Gasoline electric motors are usually lighter, smaller and quieter than diesel electric motors. Buying a home electric motor is suitable for temporary use, such as providing electricity at a picnic, a small workshop, or during outages.
Advantages of diesel electric engines

More economical price
Higher power, durability and strength
Less fuel consumption and more efficiency
Higher security and safety against fire
Lower maintenance costs
Advantages of gasoline electric motors
Easier access to gasoline fuel
The initial purchase price is more suitable
Smaller weight and volume and more portability
Lower sound level during operation
Application of gasoline and diesel electric motors
Classification of different powers of diesel electric engine
6 kW diesel generator: This generator is suitable for starting electrical appliances with low power consumption, such as small refrigerators, water coolers, televisions, and several lights. 7 kW diesel electric motor: This product is designed for industrial and welding work. It has the right power for these applications. 8 kW diesel generator: With a power of 8000 watts, this generator can meet the needs of welding and other industrial works. 10 kW diesel electric motor: This generator is used for lighting, refrigerator, TV, electric heater, chargers, mobile welding, garden use and electric motors. It can stay on continuously for 5 to 8 hours. 12 kW diesel generator: This electric engine is suitable for laboratory work, home or garden use, and small industry. 20 kW diesel electric motor: this device has the ability to turn on all household and industrial electrical consumers up to 28 amp capacity.
Investigating the difference between diesel and gasoline electric motors
Usage: Diesel electric motors are more suitable for industrial use and large-scale power supply, while gasoline electric motors are considered a more suitable option mainly for non-industrial and low-volume uses. Fuel consumption: The amount of fuel consumption in diesel electric engines is lower than gasoline electric engines. Due to the higher cost of gasoline and its higher emissions, the use of gasoline electric motors is less economical. Longevity: Diesel electric motors have a longer life than gasoline electric motors. Weight: Gasoline electric motors are lighter in weight and portable, while diesel electric motors are heavier. Safety: Diesel is less flammable than gasoline. Therefore, diesel electric motors have higher safety. Noise: The noise level of diesel electric motors is higher than gasoline electric motors. In residential areas, the use of gasoline electric motors is recommended. Maintenance: Electric motors are usually kept for emergencies and should always be ready for use. Due to their higher heat generation and simpler design, diesel engines wear out later and require less maintenance and repair (approximately every 6 months to 1 year). But gasoline engines require service at shorter intervals and are more difficult to maintain. Cooling system: In gasoline engines, an air cooling system is usually used, while in diesel engines, a water cooling system is common, which costs more.
