SEQUIN - Conversion Technology Offered by SLEEGERS
SEQUIN LPG Dual Fuel Sequential Injection System
SEQUIN is an engine conversion system that, when installed, allows the engine to seamlessly operate on propane as well as gasoline, without ANY performance disadvantages. SEQUIN technology, deployed in operating fleet applications since 2001, represents a completely new generation of technology from the underhood technology that was used in the 80’s and 90’s.
Description of the Technology
SEQUIN is a dual fuel technology:
SEQUIN is installed on the vehicle complementary to the gasoline system.
SEQUIN leverages the Original Equipment Manufacturer’s engineering.
A SEQUIN equipped vehicle does not disconnect any component of the original gasoline system.
Safety Certification:
SEQUIN utilizes certified components purchased from 3rd parties or manufactures components that are then certified by testing agencies as fit for use.
SEQUIN is a Complete Package:
SEQUIN technology is shipped for installation as a complete package for a specific vehicle platform, including tank, underhood components, fasteners, and all accessories required for installation:
- To ensure the conversion utilizes all approved components and operates as engineered.
- To ensure that the conversion is compliant with applicable legislative requirements and regulations.
SEQUIN technology is specifically packaged, programmed and certified for specific vehicle platforms. The targeted vehicle platforms are those typically used by high consumption light and medium duty fleets.
The OEM engine management system controls the operation of the engine on propane. SEQUIN provides supplementary electronic assistance and control functionality to the OEM computer. All OEM engine and emission control technology remains fully functional. Nothing is disconnected.
Operating SEQUIN-Equipped Vehicle
Starting:
The vehicle will start every time on gasoline. The vehicle is immediately ready for operation after starting, regardless of whether it is operating on gasoline or propane.
Switching from Gasoline to Propane:
After the vehicle starts on gasoline, the SEQUIN computer monitors for conditions such as propane vapour pressure and engine temperature. When conditions are appropriate, the engine automatically substitutes propane for gasoline.
The switch occurs without operator involvement or knowledge, and can vary from 20 seconds to 6 minutes depending upon various factors such as vehicle operating temperature and propane temperature. During the time before switching to propane, the vehicle can be operated normally, as there is no requirement to wait for the changeover to propane.
Should the operator inadvertently run out of propane, the vehicle immediately switches to gasoline operation, without any involvement of the driver and without any detrimental impact to vehicle performance.
Performance:
“Performance on Gasoline” is the benchmark. There are no performance disadvantages to operating a propane vehicle using SEQUIN technology.
