Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
Low fuel consumption and Euro 6-standard emissions (effective from September 2015) are also made possible by the use of Opel's "BlueInjection" Selective catalytic reduction (SCR) system, which injects AdBlue, a urea-and-water solution, into the exhaust stream. The solution decomposes into ammonia, which is then stored on a catalyst substrate.
The Theta II GDi was announced in November 2009 starting with the 6th generation Sonata, improvements include switching to GDI. Compression ratio is 11.3:1, early versions were rated at 201–203 PS (148–149 kW; 198–200 hp) at 6,300 rpm and 25.5 kg⋅m (184 lb⋅ft; 250 N⋅m) of torque at 4,250 rpm while later versions were rated at 188 PS ...
Crankcase dilution is a phenomenon of internal combustion engines in which unburned diesel or gasoline accumulates in the crankcase.Excessively rich fuel mixture or incomplete combustion allows a certain amount of fuel to pass down between the pistons and cylinder walls and dilute the engine oil.
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).
The Chevrolet Equinox is a crossover SUV introduced by Chevrolet in 2004 for the 2005 model year. It was intended to replace the North American Chevrolet Tracker and Chevrolet S-10 Blazer . The third-generation Equinox also replaced the first-generation Chevrolet Captiva .
The gasoline direct injection version of the 6G74 was launched in April 1997 as the first GDI V6 engine ever produced. It differed from the basic 6G74 in many ways apart from its unique fuel injection system—it had a crown-curved rather than flat piston head, upright intake ports rather than angled, and a 10.4:1 rather than a 10.0:1 ...
The Smartstream G1.0 T-GDI is a turbocharged inline 3-cylinder engine with gasoline direct injection (GDi); the engine makes 120 PS (118 hp; 88 kW) at 6,000 rpm and 17.5 kg⋅m (127 lb⋅ft; 172 N⋅m) of torque between 1,500 and 4,000 rpm. A detuned version with 100 PS (99 hp; 74 kW) between 4,500 and 6,000 rpm is also available for some ...
