And that pioneering Lucas fuel injection which Triumph later gave up on had its own issues. But don't just pick on Triumph. A TR6 tested today is likely to be >40 years old. If not solicitously preserved with parts replaced as necessary, it will be well down on power compared to where it was 40 years ago.
The new removable hardtop for the TR6 was designed in-house by Triumph, and was available as an option. [5] Construction of the TR6 was traditional body-on-frame with four-wheel independent suspension, front disc brakes and rear drum brakes. All TR6s were powered by Triumph's 2.5-litre straight-6 engine. The TR6 featured a four-speed manual ...
The TR6, made from 1969 to 1975, used the TR5's engine, [4] detuned to 125 bhp (93 kW; 127 PS) in 1973. [7] with a 106 hp version of the TR250's engine in the United States. [7] The fuel-injected 2.5 litre engine became available in the 2000 unit body as the 2.5 PI in 1968; [8] this was supplanted by the twin-carburettor 2500 TC in 1974. [4]
Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI), [1] is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. [2] LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions. [3]
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
Two different models were made: the TR250 with two Stromberg carburettors for the US market, and the TR5 with Lucas fuel injection for the rest of the world. [17] Both the TR250 and the TR5 were replaced by the TR6 in 1968, with the US version continuing with carburettors. [17] The main difference between the TR6 and the TR5 it replaced was its ...
Electronically controlled mechanical fuel injection. The engine control unit (ECU) may be either analog or digital, and the system may or may not have closed-loop lambda control. The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.
Fuel injection is a very broad term, covers many fuel types, injector types and many different placements of the injectors. Gasoline injection is one particular variation of fuel injection. It involves a specific fuel (gasoline/petrol) that is injected directly into the cylinders - it requires a hole in the cylinder head into which the injector ...
