ShockerEDGE is the newest technology in more than 50 years to control a diesel engine runaway. ShockerEDGE is also the first of its kind to control a spark ignited gasoline engine.

ShockerEDGE is a Patent Pending advanced technology that uses Molecular Property Spectrometer (MPS) flammable gas sensor in conjunction with our own ShockerEDGE brand engine control, MPS sensor is unlike any other previous gas sensor technology (Catalytic Bead or NDIR which use a “k-factor” multiplier to convert raw sensor signals to gas concentrations in % LEL. These “k-factors” are based on known relative sensitivities of these sensors to different gases. A single “k-factor”, corresponding to a particular gas, must be selected manually during system setup; if the sensor is then exposed to a gas other than the one selected, significant error in reported concentration can occur.

The MPS sensor is 100% digital and does not require daily bump testing with costly bump gas, does not require frequent re-calibration by an instrument tech, and does not poison/foul, necessitating replacement. The MPS Sensor calibrates itself every 2.0 seconds to report continuous accurate hydrocarbon readings, including accurate air quality information, temperature, humidity, and pressure. The MPS Flammable Gas Sensor applies a real-time conversion factor automatically, using the latest measured thermal properties of the ambient air/gas and the environmental conditions. The %LEL values reported for the bulk, which may contain a mixture of gases, achieves the same high levels of accuracy achieved with single gases.

The sensor also automatically outputs the class of flammable gas present, according to the following categories:

  • CLASS 1: Hydrogen: Molecular Weight: 2.0 [g/mol] Density: 0.09 [kg/m3] Number of Carbons: 0
  • CLASS 2: Hydrogen Mixture: Avg. Mol. Weight: 1-14 [g/mol] Avg. Density: 0.1-0.6 [kg/m3] Number of Carbons: varies This classification is unique as it guarantees the presence of hydrogen and another flammable gas
  • CLASS 3: Methane/Natural Gas: Avg. Mol. Weight: 16 to 19 [g/mol] Avg. Density: 0.6-0.9 [kg/m3] Typical Number of Carbons: 0-2 Gases having molecular properties like that of methane may be classified as methane (e.g., ammonia, acetylene)
  • CLASS 4: Light Gas (or Light Gas Mixture): Avg. Mol. Weight: 25 to 75 [g/mol] Avg. Density: 1.2-2.5 [kg/m3] Typical Number of Carbons: 1-4 Example Gases: Ethane, Propane, Isopropanol
  • CLASS 5: Medium Gas (or Medium Gas Mixture): Avg. Mol. Weight: 50 to 120 [g/mol] Avg. Density: 1.5-4.0 [kg/m3] Typical Number of Carbons: 2-8 Example Gas: Pentane
  • CLASS 6: Heavy Gas (or Heavy Gas Mixture): Avg. Mol. Weight: 80+ [g/mol] Avg. Density: 3.5+ [kg/m3] Typical Number of Carbons: 6+ Example Gases: Octane, Toluene, Xylene

The ShockerEDGE controller reads the MPS sensor, which we mount in the engine clean air intake stream, and interprets the data into engine control, and visual display information. The engine control parameters are preset to warn the operator at 2.5% Lower Explosive Limit (LEL) and to turn the engine off at 7.5% LEL. This is accomplished by connecting the ShockerEDGE controller to the engine control system (ECM or fuel shut-off solenoid). When the upper LEL is reached, the ShockerEDGE controller turns off the power to the ECM or the fuel control solenoid and stops the supply of diesel fuel to the engine, stopping the engine. The engine cannot be restarted while hydrocarbons are still present inside the engine air intake system. This will occur before the engine ingests sufficient unburned hydrocarbons to sustain a diesel engine runaway situation or cause a gasoline engine to backfire and stopping ignition hazards on hot surfaces. IE: exhaust manifolds, catalytic convertors, spark generating devices. ShockerEDGE is changing site safety to new levels that have never been obtainable before by drawing and monitoring the atmosphere while the engine is running. Example: CAT C15 engine consumes 1267CFM of air.

The ShockerEDGE system can also be configured as a mobile continuous gas monitor, which does not shut the engine off. The system operates the same and will only warn the operator of any hydrocarbons the vehicle has encountered.

The display information is shown in real-time on the digital readout located in the operator’s compartment and includes the following:

All Business Marketing - Teledyne FLIR
  • Gas identification
  • LEL concentration
  • LEL Alarm Status- Green, Yellow, Red.
  • System state – monitoring, fault, check events
  • Ambient Humidity, Temperature, and Pressure
  • Event Log- Incidents & Testing
  • System status- 31 types of system self-diagnostic events
  • Details screen – set points, time, date, screen brightness, and time out.

The display will chirp/flash yellow at 2.5% LEL warning level and constant audible buzz/flash red at 7.5% LEL.

Auxiliary warning lamps and audible alarms can also be connected to the ShockerEDGE system.

We have built-in 2 simple function tests, both displayed in the system data logging screen.

Before beginning, confirm system state reads- monitoring. Our system is completely self-diagnostic with no moving parts.

  • First is a button on the face of the control module. When pressed with the engine idling, will stop the engine as if you turned the key to the engine stop position. This test proves your electronic components are functioning correctly. Shows in light brown with time and date. Engine shutdown systems only.
  • Second is sensor function. The display shows real-time sensor status refreshed every 2.0 seconds, monitoring, or fault, as well as on the data logging screen. We do recommend misting the face of the sensor every 90 days with our sensor verification spray to ensure the screen face is clear. Shows in dark grey with time and date.
