The irony here is that camless engines are relatively easy to build. The average hacker could modify a small four-stroke engine for camless. The latest to catch my attention: engine valves that operate without camshafts. For decades the idea of electronically controlled electromagnetic. The “camless” engine developed by Koenigsegg sister company FreeValve edged closer to production on Friday with Qoros’ unveiling of a.

The absence of a camshaft also means that the parasitic load on the engine is lower, which is particularly useful in large marine engines, as it can equate to a large amount of power savings. However, the move from carbs to EFI definitely happened in response to emissions issues.
I knew the design of modern IC engines was pretty-well worked out. Those that developed the EFIs pushed for some regulation to ban older models and make the customers go to them and make everyone else play catch-up.
Formula 1 engines are all camless, they use pneumatic valve actuators, so they can turn at up to 20, rpm usually more like 12, for engien efficiency. Because then you need teeny-weenier cams for those engines! The average hacker could modify a small four-stroke engine for camless camleess in their workshop.
liter ‘camless’ engine delivers hp in Qoros 3
Guangzhou Auto Show Koenigsegg Qoros. We’ll email you the latest in performance and luxury automotive news every day. The results are myriad proprietary solutions.
The only reciprocating parts are the flaps and connecting rods that are counterbalanced opposite to one another.
Now if you said rotary piston engine …. They developed an evaporative emissions test designed to fail any vehicle with a carb. Are there maybe patent issues that are preventing companies from exploring this space? However, if the valve actuators or their electronics fail, the result will be disastrous and very expensive almost always an engine replacement. You sir, win the prize! Back to the fuel injector: Could lead to some interesting cylinder configurations.
If you can think it, you can do it. I have sold several that had to go through the receiving and reflash process before I could deliver them to customers. Since the engine is run electronically and eengine mechanically, camless engines can be updated to meet new emission regulations without mechanical modifications.
The more modern way of solving valve bounce issues is to move away from poppets to desmodronics, but that adds complexity on the flipside engije reduces friction dramatically.
1.6-liter ‘camless’ engine delivers 230 hp in Qoros 3
Pretty much what I expect from you though- professing an opinion on something you know nothing about beyond repeating what you have heard from the equally clueless. Enngine is the future, today.
All the big manufacturers have experimented with the camless concept. So you would need a VERY fast secondary safety shut off.
Camless piston engine – Wikipedia
Once electricity is disconnected, the core may still be moving due to its inertial mass. Take the CAFE standards for example. Add a power source and some calmess. The photo above showing the 2 timing chains on that engine… one of the high end Dodge now RAM pickup engines has 3 timing chains, a failure of any one of camlless munches a lot of components. The recent VW case is proof that manufacturers will attempt to find any way to get an edge- legal or not:
