POWER FUEL STRETCHER O2 SHIFTER
This Electronic Fuel Injection “piggyback” controller reads the injection signal, and the Throttle Position (TPS). The Injector signal is then “stretched” by a programmable amount, depending on the TPS. A “Synthetic” oxygen signal (O2) is generated to keep the stock Electronic Control Unit (ECU) from over-correcting, or going into a limited power “safe” mode. The Oxygen shifter (O2 Shifter) is a fuel saving device for fuel injected vehicles using a narrow band O2 sensor. The device is placed in-line with the standard O2 sensor, and intercepts the O2 sensor voltage. The device puts out a signal to the native ECU mimicking the O2 sensor signal, however the lean- or rich-transitions can be delayed (ie. shifted) by a short amount of time, typically 0 to 500ms.

 

HYBRID ELECTRIC VEHICLE SYSTEM EFI LPG/CNG KIT
This system is a complete Electric Vehicle including Electric Traction Motor, Motor Controller, Batteries and Charger. The Motor is coupled to a tire running on a chassis dynamometer for measuring the vehicles speed, torque and power, while controlling the load on the vehicle. The Hybrid Generator consists of an internal combustion engine coupled to an Integrated Starter/Generator. Our kit is available as a "DIY" for interested individuals. For fleet owners or distributors please contact us directly for full installation and tuning support. It can be installed by any competent mechanic or clever individual who can handle things such as soldering wires and tuning wrench.

 

 

ENGINE / VEHICLE TESTING OPTIONAL EQUIPMENT

Wide Band O2 sensor with display and Analog Output can be programmed to display AFR (for spark ignited engines) or Lambda (for diesel engines).
High-Temperature Thermocouple good to over 900C.
Our Throttle Servo Motor accepts the Throttle Position signal from our Dynamometer Controllers and can be easily fitted to almost any engine for automatic control of the throttle.
Combustion Analysis allows measurement of in-cylinder pressure during combustion events to determine combustion characteristics such as ignition delay, peak pressure, rate of heat release, combustion stability.
Exhaust Gas Analysis allows you to determine the emission of pollutants, including NOx, CO, Hydrocarbons and CO2 in terms of grams per kilometer.
Engine Tuning is strongly dependent on intake and exhaust manifold dynamics. With our Intake and Exhaust Manifold pressure sensors you can easily diagnose tuning effects for optimal engine performance.
In addition to the basic DAQ features of our dynamometer controllers, we have a range of additional DAQ units which include many “front end” amplifiers allowing direct connection of thermocouples, thermistors, load cells, high voltage probes and even current sensors.
Our digital fuel scales feed fuel weight data directly to the dyno monitor software for calculation, display and logging of fuel consumption and BSFC.
Various Engine Temperature Sensors including Thermistors and Thermocouples are also available.
The current Clamp Meter is very useful for Electric/Hybrid Vehicle Studies, as well as diagnosing Engine/Vehicle Electrical systems and faults.
This probe is used for measurements of higher voltages found in ignition systems, such as the capacitor voltage in CDI systems.
Derived from our AC Dynamometer power supply, the Variable AC power supply can be a useful item when requiring large amounts of controllable electric power, and is sometimes used as a speed control for fans and pumps at a lower cost than a VFD/Inverter.
Derived from our DC dynamometer power supply, the Variable DC power supply can supply up to 3A at 100VDC for various electric power applications.
Engine dynamometry is complemented by on the road measurements made with a Vehicle Data Logger. The VDL can measure many different vehicle parameters including engine and vehicle speed, acceleration, temperature, fuel flow rate, exhaust gas emission, GPS and more.
The Mobile Emissions Test System is a combination of the Vehicle Data Logger and many additional sensors, including exhaust gas emissions, designed specifically for measuring on the road emissions and determining exhaust gas emissions factors.

 

SURPLUS EQUIPMENT

This is a 3-phase voltage rectifier/regulator for small vehicle applications. The 3-phase AC signal is internally rectified, and regulated for charging a 12V battery system. It designed for motorcycles and “tuk-tuks”.

The throttle body Type 71 was developed for use in 2-stroke engines in scooters. Good for smaller (30-120cc) displacement 2- and 4-stroke engines using Electronic Fuel Injection. The throttle body has an integrated 4-pin throttle position sensor and a fixed gear rewind direction.

Specifications:
1) Valve diameter: 20 mm
2) Overall length: 75 mm
3) Motor connection outer diameter: 24 mm (Inner Diameter: 18mm)
4) Filter connection outer diameter: 35 mm
5) Minimum air flow: 10.9 to 19.2 kg / h at 0.1 bar differential pressure
6) Housing material: Plastic

This fuel rail includes a gasoline fuel injector and is used in small vehicles (motorcycles, tuk-tuks of 30-200cc) with the Synerject Direct Injection system. The fuel injector is supplied with gasoline at moderately high pressures (5 bar) and compressed air (from a small crankshaft driven air compressor). The air “blows” the gasoline into the combustion chamber via a direct injection valve (Strata 1, sold separately). There is an internal regulator for fuel pressure-air pressure. Connections are: Fuel In, Fuel Return, and Air In (bottom connection in left side foto). Can be used on and gasoline (and probably other liquid fuel) Fuel Injection applications.

Specifications:
Injector Resistance:    2 ohm (approx)
Voltage:                12V nominal
Overall Weight:         273g
Overall Length:         106mm (approx)
Overall Height:         68mm (approx)
Mounting Holes (2)    5.5mm diam 50mm apart

* New Old Stock (unused)!

This is a plastic encapsulated variable reluctance sensor used in motorcycles as the trigger signal for the Capacitive Discharge Ignition (CDI) system. It consists of a permanent magnet, pickup coil and soft magnetic core. It provides a positive/negative pulse (one pair per tooth on the rotating target wheel) of ~1V to >20V for synchronization of the spark and the engine. It can be used to trigger other things like fuel injection systems. Note: this is NOT the high-voltage source for the AC type CDI units.

Specifications
Resistance:      120ohms (+/- 10%)
Weight:          34g

* New Old Stock (Unused)!

Good low impedance gaseous fuel or liquid/air fuel direct injector. Direct Injection means the injector sits in the head, and sprays fuel into the combustion chamber directly (ie. not port injection). Widely used on converting 2-stroke engines to direct injection.

This gasoline fuel pump is used in small vehicles (motorcycles, tuk-tuks of 30-200cc) with the Synerject Direct Injection system. The pump is a piston-type positive displacement pump developing relatively high pressures (over 5 bar) for “air assist direct injection”. Can be used on and gasoline (and probably other liquid fuel) pumping applications.

Specifications
Current:                150mA (no load)
