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 Opel Corsa is a supermini car [1] [2] [3] manufactured and marketed by Opel since 1982 — as well as other brands, namely Vauxhall, Chevrolet, and Holden..

The 2019 facelift of the Opel/Vauxhall Astra K included a new 1.2 3-cylinder turbo with 110, 130 or 145 hp but this is not the PSA PureTech engine. This engine is part of GM ’s E-Turbo range and had already been extensively developed at by GM for the 2019 Astra before PSA purchased the company.
The Vauxhall Astra and Opel Kadett, for example, were both called Astra from 1991 onwards and the Vauxhall Nova (Opel Corsa A) assumed the Corsa name for its next generation in 1993. The change was completed in 1995 when the Vauxhall Cavalier Mk 3 (Opel Vectra A) was replaced by the Opel Vectra B, called Vauxhall Vectra .
The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall.
The engine first appeared in the Opel Rekord B in 1965, and was largely replaced in four-cylinder form by the GM Family II unit as Opel/Vauxhall's core mid-size engine in the 1980s, with the six-cylinder versions continuing until 1994 in the Omega A and Senator B.

The GM Small Gasoline Engine (SGE) is a family of small-displacement, inline three- and four-cylinder gasoline engines ranging from 1.0 L to 1.5 L, developed by Adam Opel AG, Shanghai Automotive Industry Corporation (SAIC), MG Motor (MG), Shanghai GM (SGM), and the Pan-Asia Technical Automotive Center (PATAC).
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
