ED has 4 types of engine. 2 for gasoline (gamma 1.6, beta-2.0). 2 for Diesel CRDI (U-1.6, D-2.0). Gamma gasoline engine is used for Cerato F/L. It is following engine for alpha II. Beta 2.0 engine is changed a little. U engine is applied for Cerato F/L and D engine is used for KM(Sportage), MG(magentis), UN(Carens).
.
All gasoline engine (Beta 2.0, Gamma 1.6) has a CVVT system. U-1.6 VGT and D-2.0 VGT are EURO IV emission engine which has additional components compared with EURO III emission engine.
2.1 General information
Gamma engine called alpha III is following of alpha II. Many mechanical components are changed but EMS is same as alpha II. gamma engine use BOSCH EMS.
Below things are gamma’s main features :
1) Reverse position for intake, exhaust manifold
- Similar as the theta engine intake manifold is located in forward to improve cooling efficiency and repair ability.
2) Offset crank shaft applied by 10mm
- To increase inertia moment offset crank shaft is used.
3) High pressure casting aluminum block and ladder frame
- To increase coherence add more ribs and cylinder block is made from aluminum.
4) Serpentine belt
- One belt type driving belt is applied.
5) Timing chain
- Timing chain rotate intake and exhaust camshaft at the same time same as theta.
6) CVVT
- Denso CVVT is applied. (Beta, gamma, theta CVVT are same mechanically but operating range is different.
7) Direct driven valve train [solid tappet]
- MLA (Mechanical Lash Adjuster) type valve train is applied.
8) Plastic intake manifold
- Length/Cross-sectional shape is optimized for enhancing torque at all rpm zone.
- As the material is changed (aluminum ⇒ plastic), the air flowing resistance is enhanced so the output and torque is increased
9) Stainless steel exhaust manifold
- Stainless steel exhaust manifold is applied to prevent from cooling down the exhaust gas temperature quickly.
