The LPEFI® is a dedicated multi-port fuel injection system for modern engines. Propane is injected in a liquid state, which eliminates the need for a troublesome vaporizer or regulator, reducing problems such as backfires and improving cold start performance.
Our unique, self-cooling fuel injectors are specially designed for liquid propane and are 100% compatible with the stock PCM.
The LPEFI® system uses specifically engineered tanks equipped with a Liquid Propane Delivery Module (LPDM) designed for easy bolt-on installation.
Bi-Phase holds the patents for every part of the system, incorporating over 100 individual claims.
Our certifications are on-highway heavy duty engine certifications. These are applicable to vehicles with a GVW >14,000 or an incomplete vehicle. Certification includes meeting both EPA and CARB requirements.
