Toyota is one of the automotive brands offering non-interference engines.
So the Toyota non interference engine list is necessary to help you identify which is the best automotive engine for your buddy.
However, this brand includes various types of engines with different features and superior functions. Thus, it can feel difficult to categorize your engine.
This article covers useful information about each type and makes a complete list to get the best pick. Scroll down for details!
What Cars Have Non Interference Engines?
The non-interference engine’s working mechanism depends on the movement of the crankshaft and the piston. The smoother the movement is, the better the engine operates.
In other words, there is a piston at the top dead center in a non-interference engine to avoid interfering with the valves when they fully open, hence the name.
Below is a non interference engine list of vehicles.
Acura is the first brand with SLX, 2.4L DOHC, 2.5L 4 Cyl, 3.0L SOHC 12 Valve, and Chrysler 1.7L, 2.2L SOHC Non-Interference.
Ford is the second brand with 9 non-interference engines such as 1.6L DOHC, 1.3L, and 2.0L DOHC Non-Interference.
Toyota brand comprises 13 non-interference engines, including 1.5L, 1.6L DOHC Non-Interference (Valves), 1.6L SOHC, 1.8L 7AFE, 4AFE, 4AF, 2.0L, 2.2L, 2.5L.
Other common brands coming with non-interference engines are Subaru, Suzuki, Volkswagen, and Volvo.
