Pressure Sensors
PRESSURE SENSORS Pressure Sensors Pressure sensors are used to measure intake manifold pressure, atmospheric pressure, vapor pressure in the fuel tank, etc. Though the location is different, and the pressures being measured vary, the operating principles are similar. Page 1 © Toyota Motor Sales, U.S.A., Inc. All Rights Reserved. PRESSURE SENSORS Manifold Absolute Pressure (MAP) Sensor In the Manifold Absolute Pressure (MAP) sensor there is a silicon chip mounted inside a reference chamber. On one side of the chip is a reference pressure. This reference pressure is either a perfect vacuum or a calibrated pressure, depending on the application. On the other side is the pressure to be measured. The silicon chip changes its resistance with the changes in pressure. When the silicon chip flexes with the change in pressure, the electrical resistance of the chip changes. This change in resistance alters the voltage signal. The ECM interprets the voltage signal as pressure and any change in the voltage signal means there was a change in pressure. Intake manifold pressure is a directly related to engine load. The ECM needs to know intake manifold pressure to calculate how much fuel to inject, when to ignite the cylinder, and other functions. The MAP sensor is located either directly on the intake manifold or it is mounted high in the engine compartment and connected to the intake manifold with vacuum hose. It is critical the vacuum hose not have any kinks for proper operation. Page 2 © Toyota Motor Sales, U.S.A., Inc. All Rights Reserved.

Developments in Precision Power Train Sensors
109 Hitachi Review Vol. 63 (2014), No. 2 Developments in Precision Power Train Sensors Keiji Hanzawa OVERVIEW: The fuel economy and emissions performance demands on Shinobu Tashiro vehicle power trains are becoming more stringent for reasons relating Hiroaki Hoshika to global environmental protection and the rising price of oil. There has also been a change in thinking on the measurement of emissions and Masahiro Matsumoto fuel economy toward allowing for conditions where the temperature and humidity are closer to real driving conditions. Other changes include the electrifi cation of power trains, such as in hybrid vehicles, and improvements in the running effi ciency of internal combustion engines that result in more frequent use of engine operating modes in which sensor operation is more diffi cult, such as the Atkinson cycle. Hitachi Automotive Systems, Ltd. is supporting ongoing progress in power train control by making further improvements in sensor accuracy. INTRODUCTION Automotive power trains have made rapid progress HITACHI supplies customers around the world with on electrifi cation and reducing fuel consumption in a variety of systems for the driving, cornering, and recent years. This article describes advances in the braking of vehicles. By using a range of different performance of the sensors used in these power trains, sensors to determine conditions in the power train, looking at micro electromechanical system (MEMS) vehicle body movements, and what is happening air fl ow sensors that reduce the error in intake pulsation, around the vehicle, these systems ensure a driving the integration of air intake relative humidity sensors experience that is safe and comfortable, and that is and pressure sensors, and the adoption of digital signal conscious of the global environment (see Fig.

Cranfield University T Fong Maf to Map Based Engine
CRANFIELD UNIVERSITY T FONG MAF TO MAP BASED ENGINE LOAD ANALOGY CONVERSION SCHOOL OF APPLIED SCIENCES MSc THESIS CRANFIELD UNIVERSITY SCHOOL OF APPLIED SCIENCES MSc THESIS Academic Year 2007-2008 T FONG MAF to MAP based engine load analogy conversion Supervisor: J Nixon September 2008 This thesis is submitted in partial 40% weighting fulfilment of the requirements for the Degree of Motorsport Engineering and Management © Cranfield University 2008. All rights reserved. No part of this publication may be reproduced without the written permission of the copyright owner. ii Abstract In motorsport, high engine power output and engine responsiveness are often desired in order to gain competition advantage. The engine tuner will normally upgrade the standard vehicle with aftermarket components such as a higher rating turbo, a longer duration camshafts, and an exhaust system. As a result of the modifications, some of the standard sensors/actuators are not able to work efficiently. For example, air reversal flow and venting of excess air pressure caused by the aftermarket tuning devices can affect the reading accuracy of the mass air flow (MAF) sensor. This thesis is to develop an Engine Control Unit (ECU) system, which will replace the MAF sensor with a manifold absolute pressure (MAP) sensor to calculate the air flow into the engine. Enduring Solution Limited (ESL) seeks to develop the MAP based system into their existing programmable ECU, thus improve their market position. The challenge of the newly developed system is to be economically viable by minimising hardware and software alterations. The approach is to modify and correlate the load analogy in the system embedded code, while retaining the other comprehensive code designed by the original manufacturer.

The LS Street single-plane intake manifolds are produced for street and performance engine applications, 5.3 to 6.2+ liter displacement, and maximum engine speeds of 6000-7000 rpm, depending on the engine combination. The Street single-plane design provides the lowest carburetor/throttle body flange height possible while providing maximum performance to 7000 rpm. These intake manifolds are sold for (pre-emissions control) applications only and will not accept stock components and hardware. EMISSIONS EQUIPMENT: Holley LS Street single-plane intake manifolds do not accept any emission-control devices. This part is not legal for sale or use for motor vehicles with pollution-controlled equipment. IGNITION CONTROL: For intake manifold P/N’s 300-270 and 300-270BK, retrofit carbureted or throttle body EFI applications, ignition control will need to be accomplished with a separate ignition control module. It is recommended to use an MSD 6LS ignition controller, MSD P/N 6012 for LS7 (58 tooth crank trigger engines). The MSD ignition controller will function with the OE crank trigger, cam timing sensor, and coils.

In 2011, the United States of America imported 45% of its petroleum from other nations [1]. In addition, efforts are being made to identify more eco-friendly options for fuel to serve as gasoline alternatives. One such fuel, which could decrease the United State dependence on foreign oil while helping the environment, is natural gas. An abundance of natural gas is found in the United States, and the burning of natural gas in internal combustion engines (ICE) releases less pollution and greenhouse gas emissions than gasoline. One of the most complex parts of natural gas ICE is the electronic fuel injection system. These systems are controlled by an electronic control unit (ECU), which is essential for optimizing engine efficiency, performance and emissions. The goal of this research was to reconfigure a hybrid-electric vehicle for compressed natural gas usage. ! ! "! ! ! ! !

Edelbrock Superchargers
TECH ARTICLE TECHApplication: DISCUSSIONEdelbrock Superchargers E-Force Boost Measurement (Installing A Boost Gauge Or Pressure Tranducer) 1. The TMAP sensor mounted on top of the manifold at the rear of the driver's side, outputs a 0-5 volt signal through pins 1 & 2 (pin 1 is signal & pin 2 is signal return,) that can be converted to an absolute pressure reading using the below calibration curve. Use of this signal requires an ambient pressure correction for calculating boost pressure. Voltage Pressure 0.62 2.70 0.80 3.69 1.09 5.70 1.40 7.69 1.71 9.70 2.17 12.70 2.46 14.70 2.70 16.21 2.94 17.70 3.25 19.71 3.55 21.70 3.84 23.71 4.15 25.70 4.46 27.70 4.76 29.70 2. The second option is to utilize the pressure port at the rear of the passenger side intake runner flange. Your supercharger has been pre- drilled and tapped for a 1/8" NPT fitting. There is currently a plug sealing the hole, which can be removed, and replaced with a fitting to adapt to your sensor. CAUTION: Never cut into the vacuum lines leading to the fuel rail pressure sensor and bypass actuator, on the driver's side of the manifold, for the purpose of tapping in a boost gauge. Interruption of the vacuum signal to the fuel rail pressure sensor can affect the fuel pressure reading to the PCM, which can result in engine failure! Furthermore, this port reads pressure before the intercooler, and therefore is before the inherent intercooler pressure drop.
