The TLX Solution

Our engineers helped devise a component that applies pulse width modulation (PWM) to emissions control system in a vehicle. As vapors from a vehicle's fuel system are stored in a charcoal canister, the solenoid valve (designed and manufactured by TLX) proportionally regulates the flow and amount of fuel vapor from the canister back into the combustion process.
