The Volkswagen FSI engine uses in-cylinder direct injection technology, which subverts the tradition of mixing oil and gas into the engine for combustion. It can inject fuel directly into the engine cylinder as needed and can achieve stratified injection.
The Volkswagen 1.8-liter TSI engine, which is produced and sold domestically, does not have a stratified injection function, but is a typical in-cylinder direct injection. The FSI engine without stratified injection retains the “uniform injection†mode of operation, which means that the engine performs uniform injection in the cylinder regardless of low or high load conditions.
In fact, stratified injection is actually an engine lean-burning technology. At low load, the Volkswagen FSI engine is half-open, and the fuel system injects fuel into the engine's compression stroke. The special piston top design creates a tumble of the inhaled air and the injected fuel, forming a theoretical space only around the spark plug. The fuel-burning air-fuel mixture is sufficient to ignite the mixture in the entire combustion chamber; and elsewhere in the combustion chamber is a thin mixture of air-rich gas to form a lean combustion.
However, the Volkswagen 1.8-liter TSI engine produced and sold domestically does not have a stratified injection function, but a typical in-cylinder direct injection. The FSI engine without stratified injection retains the “uniform injection†mode of operation, which means that the engine will perform uniform injection in the cylinder regardless of low load or high load conditions, but the injection quantity is still accurate according to the intake air volume. Controlled (the characteristics of the GDI direct injection engine) to ensure the original high power output and torque and achieve lower fuel consumption. However, due to the lack of stratified injection function, the fuel consumption of the domestic version of the FSI engine during operation will be higher than that of the engine with this function. This is not good news for users in big cities with poor traffic conditions.

How to make a request for a custom Container House? What details need attention?
Container houses can be customized and processed according to our needs. Size specifications, internal area divisions, and appearance styles can also be customized and processed. There are many different types of container houses that can be customized according to consumer needs. Custom processing. But how to put forward the corresponding requirements when customizing? What details should be paid attention to when customizing?
The overall design should be reasonable
In order to ensure the practicality of the container house, it is necessary to do a good job in the overall design when customizing the Prefabricated House. The customizable series of products need to take into account the specific floor area, internal volume, how much internal space is required, how to divide the area, etc. Generally, it is necessary to conduct on-site inspections, and to reserve the location of the corridor, etc. If the container house is used in the moving area of the construction site, then it is also necessary to ensure that the corresponding transportation channel is reserved to facilitate the staff to walk back and forth, and also to carry goods, etc., the design It is still necessary to ensure that it conforms to the situation on the spot.
Pay attention to material selection
The customizable series of products include a variety of product types. In addition to container houses, there are also custom container houses, custom light steel villas, etc. It is recommended to pay attention to the overall material of the custom. Different, the service life will definitely be affected as well. Therefore, we still have to pay attention to the specific conditions of its material. Generally, it is recommended to look at the actual product, pay attention to whether the cross section is uniform, and whether the thickness of the steel plate and the thickness of the coating are guaranteed. Moreover, we cannot ignore the details of the supporting frame, connectors and other details. We must ensure that the quality of each component is excellent, so that the container house can be used for a long time and its reliability is guaranteed.
Adjustments to blueprints
Customizable series of products may require multi-layer design, so it is recommended to make a request when customizing, and then the manufacturer will provide us with the corresponding design. If there are certain details that need to be adjusted on the design drawing, it must be completed quickly. Adjust, and then go for post-customization. Manufacturers will have their own design team, and after confirming that there are no problems in the design, they can proceed to construction.
