With perfect form, fit and function demanded by today’s technicians for both import and domestic applications, all BWD fuel injectors meet or exceed OE specifications for peak operating performance and extended service life What does a Fuel Injector do? The Fuel Injector is an electronically controlled valve that is supplied with ressurized fuel by the fuel pump and when p energized atomizes the fuel into a fine mist so that it can burn easily by the vehicle’s engine. Where are Fuel Injectors located? The fuel injector is mounted in the intake manifold so that fuel is sprayed directly at the intake valves. A fuel supply rail connects all of the fuel injectors to the fuel supply. Will a malfunctioning Fuel Injector illuminate the check engine light or affect vehicle operation? A failing sensor can illuminate the MIL and cause the engine to run too rich or lean, leading to misfire and loss of power. What are the common causes of failure? Improper fuel filter maintenance can cause the injector to clog with debris. Poor quality fuel often results in deposits on the fuel injector disrupting the fuel spray pattern.

PING)))™ Ultrasonic Distance Sensor (#28015) The Parallax PING))) ultrasonic distance sensor provides precise, non-contact distance measurements from about 2 cm (0.8 inches) to 3 meters (3.3 yards). It is very easy to connect to BASIC Stamp® or Javelin Stamp microcontrollers, requiring only one I/O pin. The PING))) sensor works by transmitting an ultrasonic (well above human hearing range) burst and providing an output pulse that corresponds to the time required for the burst echo to return to the sensor. By measuring the echo pulse width the distance to target can easily be calculated. The PING))) sensor has a male 3-pin header used to supply power (5 VDC), ground, and signal. The header allows the sensor to be plugged into a solderless breadboard, or to be located remotely through the use of a standard servo extender cable (Parallax part #805-00002). Standard connections are show in the diagram to the right. Quick-Start Circuit This circuit allows you to quickly connect your PING))) sensor to a BASIC Stamp® 2 via the Board of Education® breadboard area. The PING))) module’s GND pin connects to Vss, the 5 V pin connects to Vdd, and the SIG pin connects to I/O pin P15. This circuit will work with the example program Ping_Demo.BS2 listed on page 7. Servo Cable and Port Cautions If you want to connect your PING))) sensor to a Board of Education using a servo extension cable, follow these steps: 1. When plugging the cable onto the PING))) sensor, connect Black to GND, Red to 5 V, and White to SIG. 2. Check to see if your Board of Education servo ports have a jumper, as shown at right. 3. If your Board of Education servo ports have a jumper, set it to Vdd as shown. 4. If your Board of Education servo ports do not have a jumper, do not use them with the PING))) sensor. These ports only provide Vin, not Vdd, and this may damage your PING))) sensor. Go to the next step. 5. Connect the servo cable directly to the breadboard with a 3-pin header. Then, use jumper wires to connect Black to Vss, Red to Vdd, and White to I/O pin P15.
