Cummins ISF2.8S5129 Engine Overview
The Cummins ISF 2.8 engine is a turbocharged four-cylinder diesel engine, the smallest and lightest engine in the ISF engine family. ISF 2.8 is a modern engine that combines two main qualities – power and compactness. It is the optimal choice of powertrain for light commercial vehicles such as pickup trucks, trucks, vans, trucks. Known in the US market as Cummins R2.8.
The Cummins ISF 2.8 has a cast iron cylinder block with replaceable liners. This gave high strength with less metal use. Inexpensive traditional material ensures long-term reliability and repairability. ISF 2.8 also has a cast iron cylinder head. At the center of each cylinder are 4 valves, a single chain-driven overhead camshaft and fuel injection nozzles. The camshaft drives the valves with rocker arms (short for intake valves, long for exhaust). All valves are made of high temperature resistant steel and have a chrome plated stem. The intake and exhaust valves look the same, but are not interchangeable. The timing chain and tensioner are located on the flywheel side. The chain does not require maintenance during the entire life of the engine.
The 2.8 liter diesel is equipped with a high-quality common rail injection system with electronic control. This system is powered by a high pressure fuel pump mounted on the front of the engine. The fuel pump is driven by the camshaft via a gear. ISF 2.8 comes with a HE 200 WG turbocharger without intercooler. This diesel is equipped with safety devices for starting at low temperatures. An electric coil heats the air into the intake manifold.
