I42

I42 is a designation used primarily in the automotive industry to refer to a specific engine code, most notably associated with the **Mercedes-Benz OM642** diesel engine. This engine variant was developed by Mercedes-Benz and is part of the company’s OM series of diesel engines, which are widely used in commercial vehicles, trucks, and some luxury cars.

The OM642 engine was introduced in the late 1990s and became a key component in Mercedes-Benz’s heavy-duty trucks, particularly in models like the **Actros** and **Sprinter** series. It features a turbocharged, common-rail direct injection system, producing power outputs ranging from approximately 200 to 300 horsepower (depending on the specific variant) and torque levels up to around 600 Nm. The engine is known for its efficiency and reliability, making it a popular choice in the commercial vehicle market.

Beyond Mercedes-Benz, the I42 designation has also been applied to other engine models, such as those used in some European and Asian commercial vehicles, though these variations may differ in specifications and applications. The term remains a reference point for engineers and industry professionals when discussing diesel engines of this generation.
