Volvo Penta was founded in 1907 in conjunction with the production of the first marine engine, B1. The Penta company soon became an established internal combustion enginemanufacturer, which in 1927 delivered the engine for Volvo’s first passenger car.
Volvo acquired Penta in 1935 and Volvo Penta has been part of the Volvo Group since then. It now provides internal combustion engines (ICEs) and complete power systems to the marine industry, power-generating equipment, and similar industrial applications. The business also manufacturers sterndrive and inboard drive systems such as the Volvo Penta IPS. The engine program comprises petroleum fuel (diesel and gasoline) engines with power outputs of between 7.5 and 1,500 kilowatts (10 and 2,039 PS; 10 and 2,012 bhp)
Volvo Penta Engine Management System (EMS) sensors
Oil pressure/ temperature sensor: This sensor takes the measurement of oil temperature and pressure from the oil system’s main channel and sends the signal to the ECU.
Camshaft sensor: The impulses from the camshaft sensor provide the ECU the information on which cylinder is next in line for injection.Charge air pressure / temperature sensor: This sensor is located in the air intake manifold and monitors both the pressure and the temperature of the air entering the engine.
Coolant temperature sensor: This sensor reads the temperature of the engine coolant and sends the signal to the ECU.
Flywheel sensor: This sensor reads the crankshaft position and engine speed using ring gear in the flywheel and the signal is sent to the ECU which calculates the injection angle and amount of fuel.
Coolant level sensor: This magnetically actuated sensor detects if the coolant level in the cooling system (expansion tank) is too low.
Water monitor, fuel pre-filter: This guards against water in the fuel system and sends a warning signal to the ECU. The task of this sensor is to detect if the fuel pressure falls below a certain level.
