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.
