TD4, TDV6, TDV8: Land Rover diesel engines with Common Rail direct injection system

The TD4, TDV6, TDV8 series consist of diesel engines that Land Rover models are equipped with. These are turbo engines. They are mostly equipped with a common rail direct injection system. But there are also versions with other fuel supply systems: with direct injection and a high-pressure fuel distributor pump without a common rail, or with fuel injection into a swirl chamber. Such engines are a joint development of other car brands, such as PSA Peugeot, Citroen, Ford Motor Company and BMW. Many versions have a double turbo, which ensures maximum efficiency and performance of the engines, in addition to having excellent traction characteristics.
