To cope with the pressures, a rotor with four plungers was thought desirable.
Maximum speeds of up to 4500 rev/min were contemplated and, subsequently, medium duty engines were catered for running at about 3500 rev/min. It was designed for application to a distributor type pump to deliver at pressures of up to 1100 bar for high speed direct injection light duty engines with three, four and six cylinders up to 0.75 litres per cylinder. This system was first installed on a production engine in 1991. 7.36, was conceived in the late 1970s and design and development work on it began in the 1980s.
