The Renault G-Type was a family of naturally aspirated and turbocharged straight-four indirect injection and common rail injection diesel engines. They feature an iron block and aluminum head. The engines were in production for nearly two decades, with improvements in power and torque output and fuel efficiency.[https://www.sites.google.com/site/histoiregrouperenault/un-peu-d-histoire/histoire-des-sites-renault/cleon « Cléon — Association RENAULT HISTOIRE »] Association RENAULT HISTOIRE
