The Hyundai R engine is a diesel 4-cylinder automobile engine produced by Hyundai Motor Group, it was announced during the Advanced Diesel Engine Technology Symposium in November 2008 and began production in 2009. [1]
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).
The Smartstream G2.5 GDi is an inline 4-cylinder engine with both direct and multi-port injection and a 13.0:1 compression ratio; the engine makes 194 PS (191 hp; 143 kW) at 6,100 rpm and 25 kg⋅m (181 lb⋅ft; 245 N⋅m) of torque at 4,000 rpm in the Sonata, for the Azera and Cadenza the engine makes 198 PS (195 hp; 146 kW) at 6,100 rpm and ...
2009–2011 Hyundai Equus Hyundai Motor Company has also shown a supercharged version of the 4.6 Tau MPi engine at 2008 SEMA show, [ 3 ] and later 2009 Chicago Auto Show . This engine was equipped with a supercharger and cylinder deactivation technology to produce an estimated 460 hp (343 kW) while returning better fuel economy .
Modern direct injection diesel engines combine stratified charge (SC) with compression ignition (CI), abbreviated as SCCI. As in HCSI, HCCI injects fuel during the intake stroke. However, rather than using an electric discharge (spark) to ignite a portion of the mixture, HCCI raises density and temperature by compression until the entire ...
In September 2015, Hyundai recalled about 470,000 model year 2011-2012 Sonatas equipped with 2-liter and 2.4-liter Theta II engines. At the time, Hyundai told NHTSA that manufacturing problems left metallic debris around the engine crankshaft, causing problems with oil flow.
Fuel is supplied to the unit using Bosch 2nd-generation common rail direct injection (CRDi) through piezoelectric injectors operating at 1,360 bar (19,700 psi) for the A I series while it was increased to 1,600 bar (23,000 psi) for the A II series with the latter having been equipped with a Variable Geometry Turbocharger (VGT) with some models ...
