Direct Fuel Injection (DFI) Cayman

Porsche Cayman - Direct Fuel Injection (DFI)

Direct Fuel Injection (DFI)

Direct Fuel Injection (DFI) is featured as standard in both Cayman models. Multi-hole injectors deliver fuel directly into the combustion chamber with millisecond precision. The injection pattern has been optimized for torque, power output, fuel consumption and emissions. Combustion is even more effective as a result.

With Direct Fuel Injection , the engine management system regulates injection timing individually for each cylinder as well as the injection rate for each cylinder bank. This optimizes the combustion process and therefore fuel economy.

Depending on the engine operating condition, multiple fuel injections take place so that the catalytic converter reaches normal operating temperature sooner after a cold start and a greater top-end torque can be achieved.

DFI improves the internal cooling of the combustion chamber by having the mixture prepared directly in the cylinder. This allows for a higher compression ratio, which helps to deliver greater power output at the same time as enhanced engine efficiency. Injection is regulated by the electronic engine management system and emissions are monitored by the stereo Lambda sensors, thus helping to protect the environment.
