Toyota C engine


The Toyota 'C engine' family was a series of inline-4 diesel engines. Japanese market vehicles with diesel engines were exclusive to Toyota Japan dealerships called Toyota Diesel Shop locations from 1979 until the dealership was cancelled in 1988.
There were two earlier generations of an engine Toyota named as the "Type C". The first generation was introduced in 1940 as a modification of the Type A engine and ran on petrol. This first "Type C" was installed in the Toyota AE. The second generation “C” was the diesel engine used in the 1959 Toyota Crown CS20. None of the generations designs are related to each other.

C

The original C engine was first introduced on October 11, 1958 in a prototype Crown Diesel at the 5th Tokyo Motor Show with sales commencing on October 19th the following year. Derived from the R-series petrol engine, it has a displacement of 1,491 cc and produces. It was underpowered, and due to the use of the insufficiently strong R-series block it was also not very durable. When the new 3R engine required a re-designed block, Toyota chose to cancel the C engine rather than re-engineer it. Production ended in March 1961, and Toyota chose to focus on the more powerful diesel J engine which appeared in 1964.
