Description
D-Motor LF 26 4 cylinder and LF39 6 cylinder engines are direct drive 100% water cooled boxer side
valve engines. The engines incorporate multi-point fuel injection controlled by an advanced twin ECU
control system which is performance mapped with Lambda sensing.
A 300W/25A generator is fully integrated as standard fitment; the oil and coolant pumps are directly
driven by the camshaft. The fuel pressure is held at a constant level with a pressure regulator, which
is connected to the fuel recirculating system. Air inlet preheating is not required and not installed.
The entire motor is controlled and monitored by the ECU (

integral within the ECU housing as standard, a secondary battery and fuel pump can be installed as a
redundant system.
