Двигатель Lancia Flat 4: История и Модификации

The Lancia Flat 4 engine is an aluminum, pushrod, and later overhead camshaft, flat four (boxer) engine made by Lancia, initially for the Flavia, from 1960 through 1984. Though it was designed as a pushrod engine, it was advanced for the time. The pushrod version of the Lancia boxer was only ever used in the Flavia, and its derivatives including the Lancia 2000. In 1976, a new overhead cam engine based on a similar layout was designed and brought into production in 2 and 2.5 litre displacements for the Gamma.

The original version was the introduced in 1960; it used an bore and stroke. It was revised on 1963 with a smaller bore and a longer stroke, thus displacing A final version was introduced in 1967 with an even longer stroke coupled with a bore, giving a displacement of Production ceased in 1970.

The first 1800 was a introduced in 1962. It used an bore and stroke. One year later it was replaced by a true engine thanks to a longer stroke. In 1967 appeared the version using an bore and stroke.

The 2000 version was the ultimate Flavia engine. Bore and stroke was for a good oversquare ratio. In 1971, the 2.0 L produced , and in the HF Coupé in 1972 it produced This engine was produced from 1968 through 1974.

Lancia developed the large light alloy overhead camshaft 2.0 litre and 2.5 litre flat 4 engines specifically for the Lancia Gamma, rather than using Fiat derived engines as used in the Beta and Montecarlo and were in production between 1976 and 1984.

Replacing the 2.0 L pushrod engine used in the Flavia, the new OHC engine produced at 5500 rpm and of torque at 3500 rpm.

The engine was initially available with twin choke Weber carburetors, but in the last few years of production it was equipped with fuel injection. In both forms, it produced at 5400 rpm and torque at 3000 rpm.
