Simca Poissy қозғалтқышы: Тарихы мен дамуы

The Simca Poissy engine, commonly known as the Simca 1100 engine, was a four cylinder Overhead valve engine developed by Simca for use in its superminis and economy cars, designed by the engineer Georges Martin (V12 Matra Sports engine designer). In spite of its common name, the engine actually predates the Simca 1100 model, and debuted in 1961 in the Simca 1000. It was developed and produced by Simca (subsequently rebranded as Talbot) in the late 1960s at the manufacturer's factory in Poissy, hence its name. The engine was first designed in a form, but was reduced and stretched in order to be used in a variety of models and versions, by Simca, the Rootes Group (its partner company in Chrysler Europe), Simca's final incarnation Talbot and its last parent company Peugeot, who used it until 1991 in its midsize model, the 309. The engine existed in displacements ranging from , the biggest one on both sides of the Atlantic, powering the United States market Dodge Omni/Plymouth Horizon. Peugeot eventually dropped the engines, replacing them with their own TU family.

The Poissy engine was introduced in 1961 in the Simca 1000, a small four door saloon car. It featured a displacement of and had an initial output of , which would be increased over the years to a maximum of on the base model. The following year, the 315 was used for the first time in a two door sports model, the Simca 1000 Coupé, in a tuned form, with
The overhead valve engine Type 315 was a modern unit, with a water cooled inline design with forged crankshaft, alloy cross flow head and five main bearings. An unusual feature on early models was the absence of a spin on paper oil filter. Instead, the engine featured a form of centrifugal oil filter in the hollow rear crankshaft pulley, although all later versions used the more traditional disposable cartridge filters. One of its major innovations was the use of a swirl vortex on the intake valve port which gave very good combustion, and thus both power and economy for this time. This engine proved cheap to build, and several models of different sizes and market segments used this displacement, which survived until 1982, as the ever present entry level for the Simca 1100. In later life however, when it was installed in cars such as the Horizon and 1307/Alpine/Solara the Poissy engine was criticized for its poor mechanical refinement in particular for its excessive tappet noise, something which led to poor press reviews. It survived as the entry level engine in the Peugeot 309 until 1991.

The Poissy engine was reduced a few times, although it didn't have much use apart from the early and more compact models. In 1964, Simca developed an version for the Spanish market 1000, as cars over 0.9 L were in a higher tax bracket. This variant existed in two output levels, the most powerful of which, and two single barrel carburetors, which increased power to An even more economic version was created for the entire European market in late 1968, with only These displacements were used in the Simca 1000 up to 1978.

In 1968, another version was created for the Spanish market, the displacement. This was the first sporty version of the 1000, with power rising to A double barrel carburetor was then used in the Simca 1200 S, a coupé designed by Bertone, and the CG sports car, and could reach The regular version was later used in various models around the European market, and was even installed in the US market version of the Simca 1100, known as the Simca 1204. It was in use until 1978. The variant appeared in 1967, initially in the 1100 and then in the 1000. This proved to be one of the most popular displacements of the 315 engines, powering the LCV version of the 1100, known as VF2, and the Talbot Horizon's entry level version. It survived until 1991, when it was used as the base model to the Peugeot 309. The variant debuted in 1972, and although it wasn't very popular in the 1000, it continued to be used in various Simca and Talbot models. It was famous in racing circles, by being used to power the Simca Rallye 2, a sporty version of the 1000 introduced in 1972, with two double barrel carburetors and a maximum power of Racing versions could be tuned well in excess of , and the three generations of the Simca Rallye using this engine are still used throughout Europe, especially France, in various national rally championships for classic cars and non homologated cars. The variant was first used in 1975 in the Simca 1307/Chrysler Alpine. On virtue of its size, it could reach with a double barrel carburetor, but unlike the 1.3 L version, it was never used for racing in any capacity, Simca and Talbot preferring to use it in its larger models, including deluxe versions of the Horizon and the Solara. It also powered Europe's first soft roader, the Matra Rancho. The larger iteration of the Poissy engine was the variant. Like the 1.45 L engine, it debuted in the 1307/Alpine in 1975, and was positioned at the top of the range, initially only with an automatic transmission (the only version of the engine to feature one), necessary to ensure this engine could power the US market versions of the Chrysler Europe models. It was notorious for its use in the Dodge Omni and Plymouth Horizon, and was dubbed Peugeot by the American media, despite the fact that Peugeot had nothing to do with its design. It was also used as the base engine for the three seater coupé Matra Murena.
