Traditional gasoline engines use port fuel injection, where fuel is mixed with air before entering the combustion chamber.

Injecting fuel directly into the combustion chamber, however, lets the engine use a higher compression ratio without fear of early detonation as the fuel actually acts to cool the chamber. That can ...

Fuel smell under the hood or a stubborn check-engine light often points to a bad fuel-pressure sensor, but nothing stalls a driveway repair faster than not knowing where that tiny part hides. In most ...

A new propane direct-injection fuel system — developed through a collaboration between Stanadyne, Katech and the Propane Education & Research Council — made its public debut this week at ACT Expo 2025 ...

The direct-injection fuel system is one of several propane-powered technologies PERC is showcasing at this year’s ACT Expo. The products on display will emphasize propane’s versatility for propane ...

The global automotive fuel injection system market shows good growth owing to increasing demand for fuel-efficient vehicles, emission standards, and improving automotive technologies.

However, in a direct injection system, the fuel addition is so precise that it doesn't clean anything on its way into the engine cylinder.

Fuel injection and carburetors go about fuel delivery using markedly different processes, and these are the biggest pros and cons of each system.

According to program participant Stanadyne, the focus was on the development and testing of a direct injection fuel system using new hardware and software inhibitor technologies to remove vapor lock ...
