Global Diesel Engine Market Size, Share, & COVID-19 Impact Analysis, By Type (Heavy-Duty Diesel Engines, Industrial Diesel Engines, Marine Diesel Engines, and Automotive Diesel Engines), By End User (Industrial, Commercial, and Residential), and Regional Forecast, 2024-2032

A diesel engine is an internal combustion engine that operates on the principle of compression ignition. The air is compressed at a high temperature inside a cylindrical vessel to ignite the fuel. The chemical energy present in the fuel is converted into mechanical energy to generate heat and power. Diesel engines are also known for their high torque output, making them suitable for heavy-duty applications such as tractors, locomotives, and marine vessels. Moreover, diesel engines have high thermal efficiency owing to a high expansion ratio making them widely applicable in various sectors.

• For instance, Caterpillar Inc. diesel engines are widely used in various applications such as construction and machinery. These engines provide power and torque to operate heavy equipment in demanding job sites. Their diesel engines can also be used for off-highway trucks, locomotives, and power generation equipment.

Diesel engines are known for their high torque output, making them suitable for heavy-duty applications. They are also more fuel-efficient than gasoline engines, especially in applications requiring constant power output for a long time or distance. Moreover, factors such as the demand for reliable electricity in commercial, industrial, and residential areas are driving the growth of the diesel engine market.

Diesel engines are associated with emissions of nitrogen which have adverse effects on the environment and health impacts. Concerns about air pollution and climate change have led to stricter emission regulations. Moreover, the abundance of natural gas has led to a shift toward natural gas engines which are considered an alternative to diesel engines; therefore, it is expected to restrain the market growth during the forecast period.

IMPACT OF COVID- 19 ON THE GLOBAL DIESEL ENGINE MARKET

Due to the COVID-19 pandemic, the diesel engine market was affected in the short run. The supply chain and transportation segment was disrupted due to the lockdowns and industrial closures. It affected the availability of diesel engines and its demand. The lockdown also slowed down the growth of the diesel engine industry and affected the imports and exports of parts for diesel engines worldwide. Moreover, the pandemic highlighted the importance of sustainability and clean energy, increasing the focus on energy transition. Governments increased their support for renewable energy sources and electric vehicles. This shift affected the demand for diesel engines, particularly in passenger vehicles.
