Proton E01 engine

The Proton E01 engine, formerly known as the Petronas E01 engine, is an upcoming automobile gasoline engine by the Malaysian carmaker, Proton. Originally developed by the Malaysian oil company Petronas in 1997, the engine patents were acquired by Proton in 2012. The engine is currently being reworked in order to meet the upcoming Euro 6C, as the original engine was designed for Euro 2 standard. The E01 engine will become one of the upcoming seven engines being developed by Proton as successors of the CamPro engine family, which are expected to be ready in 2017.

The E01 engine is a 2-litre DOHC 16-valve engine featuring gasoline direct injection, aluminum block and continuous variable valve timing system. The engine is capable to produce 204.3 PS (150.3 kW) of power at 7,300 rpm and 203 N·m (150 ft·lbf) of torque at 5,300 rpm. The E01 engine can be installed 15 degrees tilting forward or backward of the engine compartment. Besides the initial 2-litre engine, the E01 engine can also be configured to spawn 1.8-litre and 2.2-litre variants.

When the E01 engine was developed by Petronas, the engine was designed to meet the Euro 2 emission standard. As a result, Proton is currently reworking the engine, in addition to the development of an all-new family of six engines, to meet the upcoming Euro 6C standard.

The E01 engine was originally developed by Sauber Petronas Engineering, a 60:40 joint-venture between Petronas and Sauber. It was the first commercial automotive engine in Malaysia. The development of the engine started in March 1997, with the engine start-up ceremony being held on 20 February 1998. The engine was intended to be supplied to Proton; however, Proton had ultimately opted for their self-designed CamPro engines instead to be used in their upcoming models. Only two known cars were fitted with the Petronas E01 engine - a Proton Satria GTi and a Proton Waja.
