Which domestic cars use Mitsubishi 4A series engines?

China Jie Jun FRV20 10 added 4A 13 and 4A9 1 engine respectively. Among them, 4A 13 engine adopts advanced and mature VVT technology, and cooperates with DIS direct ignition system with more sensitive response and more accurate control, which effectively improves fuel efficiency, and the maximum power can reach 65kw, while 4A9 1 engine is a Japanese Mitsubishi synchronous production model.

2.V3 Yue Ling

V3 Yue Ling is equipped with Mitsubishi engine 4A9 1 all-aluminum engine (Mitsubishi's most advanced small displacement engine in the world). Displacement 1.5L, wheelbase 2.5m long. Mitsubishi EVO racing training chassis and five-bar independent rear suspension are adopted.

3, Dongfeng popular Jingyi

Dongfeng popular Jingyi series includes brand-new Jingyi X5 and brand-new Jingyi S50. The length/width/height dimensions of the new car are 4515/1812/1725mm respectively, and the wheelbase has reached 2720mm. The maximum depth of the trunk storage space can reach 1690mm when the rear seats are laid down.

In terms of power, the new car is equipped with Mitsubishi 4A92 1.6L engine, matched with 5MT gearbox, with rated power of 90kw/6000rmp and peak torque of 15 1Nm.

Performance introduction of 4A9 series engines;

1 DOHC and MIVEC variable valve timing technology for double overhead camshafts

4A9 1 adopts MIVEC technology, which can not only optimize the valve opening time and phase, but also change the valve opening stroke, improve the air intake, and achieve low fuel consumption, low emission and high performance in a wide speed range. This technology is superior to Honda's VTEC and Toyota's VVTI technology, which do not have these two functions at the same time.

2. Al-Mg alloy die-casting cylinder body

Represented by Mitsubishi 4G series engines, the economical small displacement engines widely used in China are all cast iron cylinders. The use of aluminum alloy cylinder block can realize the lightweight of the engine, improve the heat dissipation capacity, acceleration performance and fuel economy, but it will reduce the yield and increase many manufacturing costs.

4A9 1 The result of applying cast aluminum cylinder block is that its overall weight is even less than 80% of 1.3 displacement 4G engine, which is basically equivalent to the 0.8-liter engine used by Chery QQ.

3. Resin material intake manifold, rocker arm chamber cover and inverted exhaust manifold.

Most conventional engines use aluminum or cast iron intake manifold, and the exhaust manifold is in front. With this design, 4A9 1 can reduce weight, fuel consumption and cost. However, there may be insufficient air intake at low speed, which needs to be compensated by careful design and adjustment. 4A9 1 solves this problem well.

4. Timing chain drive

In order to reduce the production cost, most of the old engines use timing belts, and the belts and tensioners should be replaced every tens of thousands of kilometers. Timing chain, under normal use, has a life of hundreds of thousands of kilometers, and the engine does not need to be replaced until it is scrapped.

5. Electronic throttle

The 4G 1 series engines use the traditional cable throttle, while the 4A9 series is the advanced electronic throttle. The sensor detects the signal of the accelerator pedal, and the ECU controls the DC stepping motor on the electronic throttle to control the air intake of the engine and realize the change of the speed.

Electronic throttle can not only save fuel, but also reduce the emission of harmful substances. 4A9 series engines can easily meet the most stringent Euro 5 emission standards.
