Automotive Fuel Injector Control Using Power+™ Control with Power+ Arrays™ Devices The automotive industry is faced with increasingly strict environmental regulations which require that automotive module designs include real-time monitoring and off-line fault isolation. These requirements demand that protection and fault diagnostics be present in the module to help monitor emission levels and maintain system reliability. One area that is very sensitive to these requirements is the automotive powertrain. With today’s highly specialized fuel systems, fuel injector drive is of key interest. Texas Instruments has introduced four new devices, the TPIC46L01/02 and TPIC44L01/02, that are well-suited for fuel injector control applications. The 6-channel TPIC46L01/02 and the 4-channel TPIC44L01/02 are low-side pre-FET drivers capable of serial or parallel interface. These predrivers, which can control either TI’s Power+ Arrays™ or discrete power FET’s, allow the system designer the flexibility to select the power stage that best fits the particular system load requirements. A typical engine control unit (ECU) is shown in Figure 1. The ECU receives sensor and control inputs from the engine and drives medium-current loads that require protection and fault diagnostics. In a typical engine control module, loads...
Achieve Optimal 6.0L Power Stroke® Diesel Injector Performance The 6.0L Power Stroke Diesel Engine utilizes a hydraulic injection system where high pressure engine oil is used to compress diesel fuel. The fuel injector is used to precisely control the delivery of the fuel into the combustion chamber. Following appropriate maintenance intervals and using the proper Motorcraft Original Equipment parts will ensure optimal injector durability. Normal and Special Operating Conditions: Customers use Power Stroke Diesel engines for a variety of applications, creating a need for two distinct maintenance interval schedules. The first schedule, called “Normal Operating Conditions”, applies to most personal use vehicles. The second schedule, called “Special Operating Conditions”, applies to many commercial use applications, including: Frequent or extended idling – Over 10 minutes per hour of normal driving – Frequent low speed operation – Sustained heavy traffic less then 25 MPH (40 KMH) • One hour of idle time, is equal to approximately 25 miles (40 km) of driving If vehicle is operated in sustained ambient temperatures below -10°F (-23°C) or above 100°F (38°C) Operating in severe dust or off-road conditions Towing a trailer over 1,000 miles (1,600 km) Sustained, high speed driving at Gross Vehicle Weight Rating (maximum loaded weight for vehicle operation) Use of any Biodiesel • B5 is the maximum allowable blend to be used in any Power Stroke® Diesel...
In response to Environmental Protection Agency (EPA) fuel economy and emissions regulations, fuel injection systems replaced carburetors in new vehicles in the 1980s. Fuel injectors allow more precise control of fuel than carburetors, improving fuel efficiency and minimizing emissions. However, in order to work efficiently, they must be kept clean. Because performance suffers as fuel injectors become dirty, the U.S. government mandated in the mid-1990s that all gasoline sold in the U.S. be formulated with a lowest additive concentration (LAC) level of detergent additives to help keep engines clean and emissions under control. However, it takes a very low level of additive to pass the tests, and most gasoline on the market contains as little as 123 parts per million (ppm) of additive. The low levels of detergent additives in modern gasoline allow deposits to build up on critical fuel system components, and most motorists are unaware of how dirty the insides of their engines are. AMSOIL P.i. Performance Improver is an effective one-tank, total fuel system cleaner. More potent than other fuel additives on the market, P.i. effectively cleans everything the fuel touches, including both port and direct fuel injectors, intake valves and combustion chambers, in only one single tank of gasoline, removing the deposits that have built up over thousands of miles. Removing engine deposits with P.i. effectively improves fuel economy, reduces emissions, restores power, performance and acceleration, reduces octane requirements, increases engine life and reduces maintenance costs.
1.0 OVERVIEW The HP EFI Universal Retrofit Kits (P/N 550-500 & 550-501) are designed for engines that have no off-the-shelf port fuel injection manifold available. It comes with almost all the components necessary for complete installation. Other components required are listed in this manual with guidelines for them. 2.0 SKILLS AND EQUIPMENT REQUIRED Various skills and tools are required for the complete installation and successful use of this kit. Machining for the fuel injector bungs and fuel rails requires the use of a Bridgeport mill or similar piece of machining equipment. It is nice to have a digital X/Y axis readout. The injector bungs ideally should be TIG-welded to the intake manifold, which requires an experienced aluminum TIG-welder. They can also successfully be epoxied, but welding will guarantee good durability. The fuel rails will also require tapping and/or machining depending upon the fittings chosen. Hold-downs for the fuel rails will also have to be fabricated. These should be welded to the manifold, but they can be designed to be bolted down. The tuning of the fuel injection system requires that an individual have basic computer and engine tuning skills. A manual is included that includes detailed and comprehensive tuning instructions. NOTE: This kit is a universal kit. The level of skill and fabrication required will vary for every application.

Background The web browser uses Oracle’s Java software to launch the Gradkell Systems Universal WebSigner JAVA applet, which enables your Common Access Card (CAC) to access DTS. Due to increased security within JAVA, outdated versions of JAVA will be unable to launch the Universal WebSigner applet (as well as many other applets for other websites) without lowering JAVA’s security. Check with your organization’s IT office for specific guidance. The Travel Assistance Center offers two potential workarounds, if applicable. Workarounds First, check the version installed on your workstation. Go to Control Panel, Java, and click the “About” button. The version will be displayed. Workstations using older versions of Java 7 (usually update 25) have two options. • Option 1: Upgrade to the latest version of JAVA from www.java.com. o Workstations using the latest version of JAVA will continually get error messages about whether to let the DBsign Universal WebSigner applet run but will be allowed to login to DTS. o Pay close attention to the warnings that appear and answer accordingly so the DBsign Universal WebSigner is not blocked and allowed to run. Depending on your operating system and version of Internet Explorer, the error messages may vary (see figure below.)

The design of FM receivers for broadcast reception are generally low-cost single conversion designs. The system comprises the front end, the IF amplifier plus limiter, and the detection stage. The latter two are nowadays almost always part of an integrated circuit to reduce costs. Until about the early 1990s the FM front end has always been constructed using two transistors. In a bid to further reduce costs and make the design simpler to manufacture, various manufacturers had begun to offer integrated circuits that provide a complete FM front end with just the addition of external tuned circuits. From about the mid 1990s and to the present day, semiconductor vendors have offered even greater integration, with a complete FM-AM receiver in a single chip, including a 1-watt audio amplifier, requiring minimal external circuitry. However the complete end-to-end analog design is meeting its end, as everything is moving to digital broadcasting. Nonetheless the techniques presented here remain valid, regardless of whether the radio carries analog audio or digital bitstreams. The following describes in detail, designs used for virtually all mass-produced radio sets,...
