Electronic control of diesel engines for passenger cars and commercial vehicles is a critical function in the automotive industry. Functions in modern diesel engines are controlled by an electronic control unit (ECU) that communicates with an array of sensors placed in strategic locations within the engine to monitor everything from coolant and oil temperatures to piston position to engine speed. Efficient electronic control means fuel burns more thoroughly, delivers better fuel economy, provides more power, and generates fewer emissions than past diesel engines. Modern direct-injection diesel engines produce low amounts of carbon monoxide, unburned hydrocarbons, carbon dioxide, particulate matter (PM), and reactive nitrogen compounds (NOx).
