Difference between tsi and fsi engine.

Fortunately or not, Soviet times are long gone. Now everyone can choose and buy a car to their liking, if there was money. The range of offered power plants is amazing! Among them, there are two options under the abbreviations tsi and fsi. These Latin letters mean nothing to the layman.

Meanwhile, at least half of all subsequent impressions of buying a car depend on the choice of engine.

Definition

Engine fsi - a relatively new technology for the production of gasoline internal combustion engines based on direct fuel injection.

The tsi engine is an automotive power unit with direct fuel injection and twin turbocharging.

Comparison

Both of these systems have been developed by specialists from the Volkswagen Group. The fsi engine is considered a new development, but it is older than the tsi.

The main difference with the fsi is that it is not turbocharged. The design of this power unit is based on direct fuel injection. Another fsi feature is dual fuel injection. This system is especially useful during the cold season. While the engine is warming up, enriched fuel is supplied to it.

Fsi is more efficient than a conventional engine in terms of economy, dynamics and environmental friendliness, but tsi is clearly not a competitor. This is because tsi technology includes both direct fuel injection and twin turbocharging. This successful combination made it possible to reduce the volume of the tsi engine without losing its efficiency and other qualities.
