GM Ecotec Diesel (1997)

The GM Ecotec Diesel of 1997 is a family of single-overhead-camshaft, 16-valve, turbocharged diesel engines that General Motors introduced in 1997 and used extensively in its European models. They had a single chain-driven camshaft, an aluminum cylinder head and a Bosch rotary high-pressure injection pump. A 2.0 litre version came in two outputs, badged Di and DTi by Vauxhall, with the stronger giving 100 horsepower, and a 2.2 litre version began at 115 horsepower and was raised to 125 horsepower in late 2000 with pilot injection and a variable geometry turbocharger. General Motors coded them with six characters such as Y20DTH, and the engines were replaced by the 1.9 litre GM and Fiat JTD. They powered the Astra, Vectra, Omega, Zafira, Signum, Sintra and Frontera, and Saab's 9-3 and 9-5.
