The Mercedes-Benz OM 59 is a straight-four cylinder Diesel engine produced by Mercedes-Benz Group AG, formerly known as Daimler-Benz AG. It was presented to the public in February 1933 at the Berlin IAMA, and later used in the Mercedes-Benz L 2000 series 2-tonne lorries.[2] Prior to the OM 59, automobile Diesel engines were significantly more expensive than spark-ignition options. The introduction of the OM 59 at a price of RM 1260, resulted in an increase of the proportion of diesel engines among trucks and busses.[3]
