In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.
The homologation engine, introduced in November 1982, features a 0.5 mm (0.020 in) increase in bore over the 3T, giving 1.8 L (1,791 cc). [11] With a multiplication factor of 1.4 for turbocharged engines, this equalled 2.5 L (2,507 cc) in the eyes of the FIA, placing the Celica in the 2.5–3.0 L (2,501–3,000 cc) class. The smaller 3T engine ...
