The Hyundai Mu engine is a variant of the 2.7 Liter
Delta, the main difference with the Delta engine is the inclusion of the
Continuous variable valve timing (CVVT).
General information
The Mu V6 (G6EA) is based on the Delta series and adopted some innovations of the parallel developed Lambda series , which was released in 2004 . This includes the CVVT, the changeover to mechanical bucket tappets and the almost identical cylinder head. The Mu is a 60 degree six cylinder and uses all aluminum block and heads. It features DOHC with 4 valves per cylinder, Variable intake system (VIS), Variable length intake runners (VLM) and Multi-Port Fuel Injection (MPi). The engines were built in Asan, Korea by Hyundai.
Compared to the predecessor Delta, the compression was increased slightly to 10.4, which led to an approximately three percent fuel saving (
Compression ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values.
A fundamental specification for such engines, it is measured two ways: the stati ...
). In addition, the cylinder head was modified to add a CVVT named camshaft adjustment for the intake side which enabled it to produce at 6,000 rpm and of torque at 4,000. The Mu utilizes a timing belt to drive the exhaust cams on each bank of the engine, with the intake cam sprocket driven by a chain. The CVVT mechanism in the Mu varies intake cam timing relative to the exhaust cam timing, which is fixed. This did not vary the valve lift nor duration.
In 2008, the CVVT control was updated to include the exhaust cams as well (Dual-CVVT), which enabled it to produce at 6,000 rpm and of torque at 4,500 rpm, the Kia Cadenza from 2010 to 2013 utilized this variant with unpublished changes to produce at 6,000 rpm and of torque at 4,500 rpm.
A version for LPG, (codenamed L6EA) was made for the Korean market, utilizing a Compression Ratio of 10.0, it produced at 5,200 rpm and of torque at 4,000 rpm.
