Car and performance

MIVEC ( Mitsubishi innovative Valve timing Electronic Control system)

Now i want to introduce about this engine with my knowledge which i have learn. Although this engine has been using in japan long time ago but it is quite a good performance engine which has been using in malaysian. i like it because it is not a turbo type engine.I like an NA engine. (Naturally aspirated).

1.At low speeds, a mild (low-lift) cam lobe provides stable idle, lower emissions and increased torque at lower speeds.

2.at high speed,a second set of cam lobes are activated, providing higher lift and duration; therefore a greater quantity of air into the combustion chamber which increases the power and torque output over a broad engine speed range.

There are many types of mivec :

1. mivec silver top
2.mivec black top

3. mivec Rs

4.Mivec md (same power but much more fuel economy consumption)

5.mivec turbo (hybrid)

6. mivec v6

Maximum Torque :172 bhp) @ 7,500 rpm

167 N·m (123 ft·lbf) @ 7,000 rpm

Advantage:

1. Durable engine (NA)

2.fuel Consumption good.
3. Maintenance ok than turbo

4.In highway ( more power than gsr turbo)

Disadvantages

1. spare part rare.

2. ecu(computer box) to expensive.

3.cannot modified too much than turbo.

Modification of mivec:

1. Air intake and hks air filter.

2. adjust piping 2.3' - 25' inch.

3. Rally art ecu

4. VTEC Controller ( VAFC 1 or 2)

5.Upgrade 4g93 blog.

6.Change throttle body

7. lsd gearbox

8. Add e-manage+ dyno.

9.Use adjustable campulley,upgrade high tension cable plug and and change to iridium spark plug.
