When did Porsche 911 go fuel Injected?

When did Porsche 911 go fuel Injected?

But it remained a very compact car. Mechanical fuel injection was introduced in 1969, became standard in 1974 and gave way to Bosch digital engine management in 1984.

How does Porsche MFI work?

The MFI system uses the injection pump to coordinate the amount and delivery of the fuel. The velocity stacks and throttle bodies mounted to the top of the heads regulate the airflow into the cylinders.

How does Hilborn fuel injection work?

Mechanical fuel injection works with a simple throttle-controlled air valve and a fuel pump, usually running at one-half engine speed. After pulling fuel from a vented fuel tank, the fuel is delivered through a barrel valve that controls the amount of fuel with the position of the air valve.

How does Bosch mechanical fuel injection work?

Built in an age before electronic sensors and regulators, the MFI pump uses a series of mechanical ‘sensors’ to create an ever-changing fuel map based on throttle position, engine speed and barometric pressure.

What year did Porsche introduce its 3.0 liter engine in the US?

1978. Porsche introduces the 928. It is radically different from the 911 and features a front-mounted, liquid-cooled 240-horsepower V-8 engine. The 911 becomes the 911 SC, featuring a 3.0-liter engine and a host of enhancements.

When did all 911 become turbo?

911 (1964–1989) 930 (1975–1989) the turbocharged version. 964 (1989–1994)

What is a Porsche MFI engine?

Both the 911 E and the 911 S were fitted with MFI (mechanical fuel injection) in place of carburettors, and racing versions of this engine were capable of figures in excess of 266 hp. The 2.4 litre Porsche 911 engine used a magnesium block to help keep weight down, with aluminum heads.

How does Bosch K Jetronic work?

K-Jetronic (1973–1994) K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi). The volume of air taken in by the engine is measured to determine the amount of fuel to inject.

Is Hilborn still in business?

Hilborn is gone, now and so are the fleeting memories of visiting that shop whenever we drove by the busy roadway.

Is mechanical fuel injection Streetable?

Mechanical Fuel Injection Is Not Just for Race Cars Anymore Idle or wide-open throttle, there’s no in-between. Great horsepower or horrible driveability, your only options. Since its ’40s conception, mechanical fuel injection (MFI) was strictly reserved for race cars. Street cars need not apply.

Can you run mechanical fuel injection on the street?

Mechanical Fuel Injection Is Not Just for Race Cars Anymore Great horsepower or horrible driveability, your only options. Since its ’40s conception, mechanical fuel injection (MFI) was strictly reserved for race cars. Street cars need not apply.

What is the difference between electronic and mechanical fuel injection?

Electronic control allows you to control the injection of fuel more accurately to optimise the power delivery and fuel consumption compared to mechanically controlled engines. However, in some cases, a mechanically controlled system could be sufficient for constant speed or electric power (EP) generation applications.
