What does DGI mean for engine?
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber.
What does FI DOHC mean?
FI DOHC = fuel injection, double overhead camshafts. MFI FFV DOHC = multi-point fuel injection, flex fuel vehicle, double overhead camshafts. “FFV”, a flex fuel vehicle, means the car is designed to run on E85 fuel; that’s 85% ethanol, 15% gasoline.
Is a DOHC engine good?
A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. DOHC engines also allow the spark plug to be placed right in the middle of the combustion chamber which in turn promotes efficient combustion.
Is DOHC better SOHC?
DOHC is better for performance because you will get more horsepower with it. SOHC is better for reliability. A SOHC engine contains much lesser parts, which will make it more reliable.
What is CRDI diesel engine?
Common rail is a fuel injection system found in modern diesel engines. Common rail systems provide a level of flexibility which can be exploited for class leading emission control, power and fuel consumption.
What are the pros and cons of direct injection?
Pros and Cons of Direct Injection Because direct injection delivers a concentrated amount of gas, less fuel is wasted, which saves money at the pump and is good for the environment. There’s a downside, though. A side effect of this high pressure stream of fuel is overspray lands on the intake valve and ports.
What’s the difference between Fi and MFI?
What Is The Difference Between Fi And Mfi Engine? It is essentially the difference in usage of vacuum and oil pump as they do not carry fuel into the cylinder but send it under high pressure. As a result, the former uses vacuum while the latter sprays fuel in the engine.
What is fi vs MFI?
MFI — Definition 2 The primary difference between carburetion and fuel injection is that the former uses engine vacuum to suck fuel into the cylinders, while the latter sprays fuel into the engine under high pressure.
What is the advantage of DOHC?
The first thing that a car enthusiast gets to enjoy in a DOHC engine is better performance in terms of power, torque, and efficiency. Though it highly depends on the engine horsepower. But DOHC has two cams that allow the manufacturers to place the valves in any desired place for maximum output.
Is DOHC same as VTEC?
DOHC VTEC = Same as above, but because intake and exhaust are on separate cams, you can have very wild cams timings, duration and lift for high-cam. VTEC-E = VTEC is used to close 1 intake valve at low RPM. So it operates at in 12 valve mode in low RPM for torque and 16 valve mode at middle to high RPM.
What does DOHC 16V mean?
The DOHC means dual overhead cam and the 16v refers to the number of valves in the cylinder head. Which if you divide the cylinders by the valves you’ll come up with 4 valves per cylinder.
What does DOHC mean on a car badge?
I know for a great percentage of our readership, this is like asking what your own nostrils are for, but let’s not forget that the world isn’t just populated by car nerds like us. So, for all those people, here’s what DOHC means, and it’s a pretty technical thing to wear on a car badge, if you think about it: Dual OverHead Camshafts.
What does DOHC 4 cylinder mean?
DOHC means it is a Dual Over Head Cam engine and usally DOHC 4 cylinders make more power than most SOHC (Single Over Head Cam) 4 cylinders, so it is nice to have
What does the L4 mean in DOHC?
The L4 refers to the engine design and cylinder numbers. The DOHC means dual overhead cam and the 16v refers to the number of valves in the cylinder head. Which if you divide the cylinders by the valves you’ll come up with 4 valves per cylinder.
