In addition to two valves per cylinder, the cylinder head, made of light alloy, also has unit injectors. Each unit injector combines a plunger steam pump and a fuel injection injector. The common camshaft drives both the valves and the pump-injector plunger pair, as a result of which fuel is injected directly into the engine cylinder.
