Starting problems occur when the fuel accumulator is deffective.

THE FUEL ACCUMULATOR, OR BETTER KNOWN IN AUSTRALIA AS FUEL DAMPER, is located just after the fuel pump. All K-JETRONIC systems must have this very important component fitted into the fuel supply line. The housing of the fuel accumulator is split into two parts, the same as the fuel distributor. The difference is that the top part houses a very heavy compression spring, and as well, it has a safety fuel bleed outlet or, in other words, atmospheric discharge opening. The joining point to the bottom half is a metal folding lip and houses a heavy duty diaphragm. The bottom part has internally a metal fuel deflection plate, where the inlet fuel line is connected to a metric fitting. The fuel outlet is then taken off from any part of the bottom housing, as well from a 14 mm metric fitting. The exact location of the fuel accumulator is as close as possible to the outlet of the fuel pressure pump, or main pump. This will inhibit any fuel pressure noises from the fuel pump. As we have learned, the relationship between fuel flow and fuel pressure, are constantly changing. The fuel accumulator will now assist in keeping the pressure and flow in the fuel distributor bottom half always the same. The fuel accumulator now has the ability to take into itself the reserve pressure and flow from the fuel pump. Due to the long fuel line to the engine bay, known as fuel pipe flow friction and the system pressure regulator valve in the fuel distributor head, this keeps the diaphragm of the fuel accumulator compressed and therefore stores more fuel while the pump is running. By acceleration, some of the fuel FLOW AND PRESSURE will enter the top half of the fuel distributor, which can only go ONE WAY to be discharged by the injectors. The diaphragm in the fuel accumulator can now compensate for the fuel diversion to the injectors, or fuel diversion via the system pressure relief valve. The fuel accumulator also plays the role of controlling the fuel flow ' back up '. Either to the injectors or via the system pressure valve.

The purpose of the fuel accumulator is to maintain pressure in the fuel system to prevent fuel vaporization while the vehicle is not in
use. The system has several check valves inside that close, sealing off the fuel return lines to the tank. When the accumulator gets tired or fails,  you will notice running and hot re-start problems.

Remember, your accumulator is 25+ years old, diaphragm may go any minute and spring is tired. So, the question is "WHEN  it will fail", and not "IF".

As you probably know, the 1988 Turbo has a lot of common systems with 1986 and 87 HCI Turbo. Simply speaking, it is an S3 in the Stevens body.   All of these cars are equipped w/Bosch CIS (Continous Injection System), sooner or later, will develop rust in the tanks. Modern (pump) gasoline with ethanol is very corrosive, your tanks are 24 years old and were never designed to store such an acidic liquid. 86-88 cars are very nice, but most of the time, Bosch injection system is misunderstood. Bosch CIS K-Jetronic injection system is pretty reliable, BUT it is very sensitive to contamination and therefore pressure fluctuations.

 

REMEMBER: The worst enemy of the Bosch CIS  injection system is DIRT, varnish deposits, ethanol and prolonged storage.

Above  applies to any Porsche, Saab, Mercedes, DMC, VW, Audi, BMW, Ferrari, Lamborghini, Bentley equipped with Bosch CIS K-,KE-,L-, LH-, Jetronic and Motronic injection systems.

Bentley Zagato GTZ – back in production

Fri, 19 Feb 2010

The Bentley Zagato GTZ is back in 'Production' It’s now two years since Zagato announced they were building the Bentley GTZ, a Zagato-bodied Bentley Continental GT Speed. They made the announcement at the Geneva Motor Show back in 2008 and we later discovered that they were intending building just nine cars, each of which would cost a barking mad £850,000. But despite the announcement that Zagato were going to build nine Bentley GTZs, it looks like only one or two were made.
