Ford Pinto engine
It was used in many European Ford cars and was exported to the United States to be used in the Ford Pinto, a successful subcompact car of the 1970s, hence the name which is used most often for the unit. In Britain, it is commonly used in many kit cars and hot rods, especially in the 2 litre size.

NHTSA scheduled a public hearing for June 1978, and NHTSA negotiated with Ford on the recall. 
Lee and Ermann noted that NHTSA used a worst case test to justify the recall of the Pinto, rather than the regular 1977 rear impact crash test. A large "bullet car" was used instead of a standard moving barrier. Weights were placed in the nose of the car to help it slide under the Pinto and maximize gas tank contact. The vehicle headlights were turned on to provide a possible ignition source. The fuel tank was completely filled with gasoline rather than partially filled with non-flammable Stoddard fluid as was the normal test procedure. In a later interview the NHTSA engineer was asked why the NHTSA forced a Pinto recall for failing a 35 mph test given that most small cars of the time would not have passed. "Just because your friends get away with shoplifting, doesn't mean you should get away with it too."
