What is the compression specs of a 2013 Toyota Corolla?

The 2013 Toyota Corolla had the following compression specs:
– Base engine size: 1.8 liters
– Base engine type: I-4
– Horsepower: 132 hp
– Horsepower rpm: 6,000
– Torque: 128 lb-ft.
– Torque rpm: 4,400
Please note that these specifications are for the base model and may vary depending on the specific trim level and optional features.

What is the most common compression ratio?

Typically, petrol engines have a CR of 8–10, while diesel engines have a CR of 15–20. The CR of petrol engines is limited by the requirement that the fuel burns uniformly in the cylinder and does not ignite thermally prior to the spark (so-called ‘engine knocking’).

What is considered high compression for a car?

10 to 1 was the start of high compression for the same period and usually required higher octane fuel (90 to 93 octane) to work properly. Current petrol engines, with SFI and VVT can have compression ratios of 11 to 1 and still use 87 octane fuel. Diesel engines can run 14 to 1 up to 25 to 1.

Is 140 compression good?

Since the gasoline engine has a spark plug, only moderate compression is enough, requiring about 140-160 pounds per square inch (PSI). Depending on their size and application, some engines may require a higher compression such as 220 PSI.

What are acceptable compression readings?

Most gas engine’s compression should be between 125 and 175 PSI while a diesel will generally fall between 275 and 400 PSI. Remember to write down each of your findings. If one or more cylinders looks to be way off in PSI, you can re-run the test again just to check.

Is 200 compression good?

That is, if the compression test reveals less than 90psi, that particular cylinder can be declared “dead.” On the other end of the spectrum, ~200psi is about the most compression pressure you will see in a non-racing gasoline engine.

Is 120 compression bad?

In general, a compression reading of 120 PSI or above is considered to be good for most gasoline engines. However, the acceptable range of compression values may vary depending on the make and model of the engine, as well as its age and condition.

What is the standard compression for an engine?

The compression results generally fall between 125 and 175 PSI (pounds per square inch) when there is a healthy gasoline engine. However, it depends on the make and model of a vehicle. In a diesel engine, the optimal PSI generally falls between 275 and 400, with no more than 10% variation between any two cylinders.

What is a bad compression reading?

A healthy engine should have 100 PSI per cylinder. If two cylinders next to each other both have low pressure, a blown head gasket is a likely culprit. If you discover you do have low compression, the only solution is to replace the leaking part whether it’s the piston, piston ring, camshaft, head gasket or valves.

What is the compression ratio of a 2013 Toyota Corolla?

The 1.33 litre petrol engine is equipped with Dual Variable Valve Timing-intelligent (Dual VVT-i) and a high compression ratio of 11.5:1, which increases the thermal efficiency of the engine. It generates 73 kW/ 99 DIN hp and maximum torque of 128 Nm at 3,800 rpm.

What is considered low compression in a car?

But a good rule of thumb says that each cylinder in a mechanically sound engine should have compression of 130 psi or higher. While I’ve seen some people claim 100 psi is sufficient, the gearheads and other sources I’ve consulted consider that too low. In addition, you want consistency from one reading to the next.
