In this year's Shanghai Auto Show, Chery debuted two new small-displacement turbocharged engine (1.2TGDI and 1.6TGDI), if successful mass production, the future will fill the gaps in this field Chery.
Both engines use a modular concept of development, one for 1.2L three-cylinder engine, a 1.6L four-cylinder engine for their bore and stroke are all 77mm × 85.8mm, both only a difference of a cylinder, Peugeot 5008 Cartridge so that to ensure that the cylinder structure without major adjustment for two engines, while they are all aluminum block and cylinder head material.
● 1.2TGDI
On the technical equipment, this 1.2T engine uses a relatively mainstream turbocharging system, direct injection and twin variable valve timing technology, its maximum power of 133 hp and maximum torque of 212N • m.
In order to enhance the efficiency of the engine, it is equipped with a variable displacement oil pump and electronic thermostat, while the turbocharger has also designed a separate cooling water, can guarantee after the engine flameout, through independent electric pump continues for cooling the turbocharger.
As a three-cylinder engine, the vibration is still a big problem, given Chery solution is placed parallel to the bottom of the crankshaft balancer shafts in two speed crank twice.
● 1.6TGDI
Due to the modular design concept, this 1.6T engine on the technical equipment and the 1.2T engine can be described exactly the same spatial layout of each component are also maintained the same. Its maximum power of 183 hp and maximum torque of 295N • m, as highlighted problems due to vibration, unlike three-cylinder engine, so it is not designed to balance shaft unit.
Chery has not announced the exact time for these two engines equipped with mass production as well as specific models, expected to be equipped in the main compact or mid-sized car, but these two engines is likely to become the next main models of Chery cars.
