Direct Fuel Injection (DFI) Boxster

Porsche Boxster - Direct Fuel Injection (DFI)

Direct Fuel Injection (DFI)

Direct Fuel Injection (DFI) is featured as standard in both Boxster 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.

With direct 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 conditions, multiple fuel injections can take place on each operating cycle. This allows the catalytic converter to reach normal operating temperate sooner after a cold start and a higher maximum torque to 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 higher 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.
