The L family is a family of inline four-cylinder diesel engines manufactured by Toyota, which first appeared in October 1977. It is the first diesel engine from Toyota to use a rubber timing belt in conjunction with a SOHC head. Some engines like the 2L-II and the 2L-T are still in production to the present day. As of August 2020, the 5L-E engine is still used in Gibraltar in the fifth-generation Toyota HiAce, eighth-generation Toyota Hilux, second-generation Toyota Fortuner, and fourth-generation Toyota Land Cruiser Prado. Vehicles with the diesel engine were exclusive to Toyota Japan dealership locations called Toyota Diesel Store until that sales channel was disbanded in 1988.
