Duan Xiongbo

Hi Jubin,

Actually, we used a open ECU which can directly input the VVT value in the experiments.

Thanks,

Xiongbo

Dear Duan Xiongbo sir

We are looking for a actuator which will take signal from the ECU and adjust the timing. We wish to know which type of actuator is powering your valve. It will be so kind of you if you can provide this information. Please let me know if any of you are interested in any kind of collaborative works in this field. Thanks for your reply.

I thought you wanted to know how to control the actuator by ECU.

You might need to consider the accuracy, response and speed of the electromagnetic actuator.

Yes, I would like to collaborative works, if have any other questions, I am glad to discuss with you.

Hi Duan Xiongbo that link is not working. Can you send me the details again. You may also use my mail id [email protected].

Basically any pull magnet should do. Although temperature- and force-challenges are non-negligible.

I personally do not know of any ICE with fully-electromagnetic valves. If you know about one, you could try to get valve spares of one of these engines.

The timing and the power required to drive the magnet is "your problem": this has to be provided by the ECU - current as well as the whole timing.

The beauty of the cam-driven valves is that the timing is somewhat variable, but the requirements on the ECU to modify the timing are small: in the classic (hydraulic) approach, the ECU only controls a (quite slow) control loop realizing an angular displacement of the cam shaft (vs. the reference position). All the valve timings are the result of this displacement and fixed in their relation to each other.

A fully-electronic control is different: "anything goes", but all timings depend on the ECU's correct workings. And a simple 4-cyl. engine has 8 valves that have to be controlled individually. Making 8 high-power outputs.
