For its Euro 4 and Euro 5 versions, the EE20 engine had a semi-closed block i.
At higher engine speeds, however, the vanes would open to reduce airflow resistance and improve fuel consumption.
Injection and combustion The Euro 4 and Euro 5 EE20 diesel engines had a Denso common-rail injection system with eight-hole, solenoid-type injectors that achieved an injection pressure of 180 MPa.
For the EE20 engine, the injectors were positioned at an almost 90 degree angle to the cylinder and were 40-50 mm shorter than those used in inline four-cylinder diesel engines.
As such, it does not consider the Euro 4 emissions compliant EE20 engines that were available in Europe.
The EE20 engine had double overhead camshafts DOHC per cylinder bank that were driven by a chain and gear with a speed-reducing gear.
Furthermore, cooling slits between the cylinder bores provided water cooling channels.
