Does Porsche use direct injection?
New Porsche 911 with Direct Fuel Injection and Double-Clutch GearboxCarrera and Carrera S Even More Economical and Powerful. Doppelkupplung (PDK), makes the new 911 even more sporting and dynamic.
When did Porsche switch to fuel injection?
1969
Originally an air-cooled 2.0-litre engine with Solex carburettors, the Porsche 911’s flat six engine got its first major revision in 1969 with the introduction of the B Series cars. With this came a switch to mechanical fuel injection on the 911E and flagship 911S models.
Is mechanical fuel injection still used?
Mechanical fuel injection (MFI) was developed in the early days of automotive racing and is still in use today.
What is a Porsche MFI engine?
Mechanical Fuel Injection (MFI) was initially perfected as military technology, to solve the problem of fuel starvation on carburettor-fuelled military aircraft capable of pulling high G-forces in flight.
What is Porsche DFI?
Porsche’s introduction of their DFI (Direct Fuel Injection) intake was a totally and completely redesigned intake system developed to deliver improved performance, fuel consumption and emissions by optimizing the air fuel mixture directly inside the combustion chamber.
When did Porsche fix IMS problem?
Porsche came out with their own IMS bearing replacement in 2017 using a sealed ceramic hybrid ball bearing like the IMS Retrofit, which was almost a decade after LN Engineering released the IMS Retrofit in 2008.
Which 911 models are naturally aspirated?
Porsche dropped the naturally aspirated engine from the 911 lineup, with the exception of the GT3 models, which means even the base 911 Carrera is force-fed as much air as possible. Back in early February 2022, we spotted the very first prototype of the facelifted 2023 911 Carrera doing some cold-weather testing.
What does DFI mean on a Kawasaki?
digital fuel injection
The Scag® Turf Tiger™ features a Kawasaki® 791DFI (digital fuel injection) engine option. Over the past decade, the FD Series of engines by Kawasaki has earned a reputation as a serious, professional-grade powerplant. This highly fuel-efficient DFI engine generates a substantial torque.
Is Carrera S naturally aspirated?
And, as it turns out, there’s actually a lot of desire for a naturally aspirated, road-going 911, and Porsche even admits it, but it’s just too much to handle….A Naturally Aspirated Porsche 911 Carrera Just Isn’t Feasible.

What motor does SCAG use?
The Scag® Turf Tiger™ features a Kawasaki® 791DFI (digital fuel injection) engine option. Over the past decade, the FD Series of engines by Kawasaki has earned a reputation as a serious, professional-grade powerplant. This highly fuel-efficient DFI engine generates a substantial torque.
Which Porsche has IMS bearing issues?
Which Porsche models can IMS bearing failure occur on? Boxsters, Caymans and 911s from MY1997 to MY2008 are all at risk of IMS bearing failure, with the exception of Turbo, GT2 and GT3 models. However, the type of bearings used changed over the period and some were more prone to failure than others.
What kind of fuel injection does a Porsche 911 use?
Bosch Mechanical Fuel Injection is a splendid, if not inexpensive, performance induction system. It was used on the 911S and 911E from 69 to 73 as well as the 73 Carrera RS. Porsche used various types of MFI on factory racing cars from 67 to 84.
Why is it important to take care of my Porsche injection pump?
Due care should be exercised when handling or working on these pumps as the internal parts are often very hard to replace and very expensive to buy. Therefore it is essential that your Porsche’s injection pump is well maintained to provide the excellent performance and durability that came with it from new.
What is a Bosch mechanical fuel injection system?
One of the most complicated fuel delivery systems ever created was the Bosch mechanical fuel injection system, or MFI. The system was a precursor to the more modern electronic controlled fuel injection systems, and is actually a marvel of mechanical engineering.
How does fuel injections work?
Fuel is squirted out of the injectors at a remarkably high 220-250 PSI. This high pressure aids in the atomization of the fuel, which in turn increases the surface area of the mixture. This results in a more efficient and complete burn of the fuel.
