Which is better, Mitsubishi 4b 12 or 4j 12?

Compared with 4B series, 4J series' biggest highlight is to cancel the throttle design and increase the intake stepless variable valve lift technology. In fact, generally speaking, these two points can be summed up as canceling the throttle, and the throttle signal directly controls the valve lift.

2.4L 4J 12 engine is very easy to start a new Outlander, and the throttle is light at the beginning, so it won't be too tired when driving in traffic jams in urban areas. In daily driving, the engine speed will not be too high, which is always around 1300 rpm, and the slightly accelerated speed rarely exceeds 2000 rpm. This time should be regarded as a relatively easy driving mode, with tepid power and low engine noise. At the same time, it is not difficult for vehicles to maintain medium and high speed. Even at 80km/h, the engine speed does not exceed 1 400rpm, but it is a little laborious to speed up. For example, if you need to overtake, you will feel a little overwhelmed and find a good time to step on the accelerator. At this time, due to the resistance of the gearbox, the engine is slightly delayed, and overtaking becomes not so easy.
