New rounds of stringent nitrogen oxides (NOx) emissions reduction regulations in Europe (Euro 6c) and North America (CARB LEV III, EPA Tier 3) are driving the optimization of existing diesel exhaust aftertreatment systems. Urea - Selective Catalytic Reduction (SCR) systems are among the de-NOx technologies that have been successfully introduced in recent years. The new regulations are bringing a closer look to SCR de-NOx performance particularly during the cold start phase of the existing emissions certification cycles. This presentation will review some of the options under consideration to address cold start NOx emissions. Some of these approaches impose new and more severe requirements on the urea injection function – these are also reviewed as well as the response to these requirements by the injection system designers.

Spark-plug sized particle sensors are developing rapidly due to onboard diagnostics (OBD) regulations demand in the US and Europe and eventually worldwide. Particle sensors will be one of the key enablers for exhaust particle filters to continue their success in keeping particle emissions below or equal to the regulatory limits not only in brand new vehicles, but also in vehicle lifetime. Beyond OBD, particle sensors have numerous applications in engine research and development, retrofit technologies, environmental research and modeling, and instrumentations. Before spreading the use of particle sensors in the market place, it is critical that their performance and durability are well understood. The performance of particle sensors is critical as we need to understand what property of particulate matter (PM) do they measure (mass, number, surface area, size, etc…), the fundamentals of such measurement and the dependent variables, and how it relates to our current measurement method of PM.

Abstract In this work, in-cylinder pressure was measured in a 55 cc single cylinder, 4.4 kW, two stroke, spark ignition engine. In cylinder pressure measurements were taken using two different pressure transducers to determine if the performance differences between the two transducers are discernible in a small, spark ignition engine. A Kistler brand measuring spark plug was compared to a Kistler brand flush mount high temperature pressure sensor. Both sensors employ piezo-electric pressure sensing elements and were designed to measure indicated mean effective pressure as well as to detect knock at high temperature engine conditions. The pressure sensors were installed and adjusted to ensure cylinder volume after sensor installation matched the engine's original configuration within reasonable manufacturing tolerances. A series of tests at four throttle settings ensued to determine if either device altered the combustion volume or the engine's performance. Performance measurements were obtained over a range of engine speeds from 4000 rpm to 6000 rpm.

Abstract Global concerns over pollution have led to increasingly strict emissions legislation targeting small engines, which currently pollute at a much greater level than modern multi-cylinder automotive engines. Closed-loop control may be required to meet many future legislation requirements; however, such systems can be impractical due to high added component costs. A necessary component for closed-loop engine control is an oxygen sensor. Existing automotive oxygen sensors are too large, require too much power, and are far too expensive to be suitable for the vast majority of the global small engine applications; therefore, some manufacturers have developed smaller and/or unheated versions based on their existing sensors to meet this emerging need. The ability to miniaturize resistive based sensors well below that of traditional Nernst (zirconia based) oxygen sensors affords the opportunity to meet future emissions standards with less of an impact on cost. The performance of a novel low-cost, low-power, narrow-band resistive-based oxygen sensor was compared with the stock oxygen sensor and several other commercially available oxygen sensors on a 2014 Honda Grom 125E motorcycle.

Abstract Recent concern over air quality has lead to increasingly stringent emissions regulations on ever smaller displacement engines, resulting in the application of Electronic Fuel Injection (EFI) to the 100cc-200cc class 2-wheelers in many countries. In the pursuit of ever smaller and less expensive EFI systems a number of unique technologies are being explored, including resistive type oxygen sensors. In this paper we investigate the application of a prototype resistive oxygen sensor to a small motorcycle EFI system. Measurements of the exhaust system temperatures, and Air/Fuel Ratio (AFR) and resistive sensor response are carried out, and compared to the standard zirconia oxygen sensor to create an estimate of the sensor's in-use performance. Motorcycle performance data are compared using both a standard zirconia switching type oxygen sensor, and the new resistive type oxygen sensor to control the air/fuel ratio. Results indicate that the resistive type oxygen sensor is capable of allowing the EFI controller to successfully control the vehicle's AFR in all operating modes with a significantly faster “light off” time, and lower overall current draw when compared to the standard heated zirconia sensor.

Abstract Various sensors including throttle position sensors (TPS), manifold pressure sensors (MPS), crank angle sensors, engine temperature sensors, and oxygen sensors are mounted in electronically controlled fuel injection (FI) systems to accurately regulate the air-fuel ratio according to the operating state and operating environment. Among these vehicle-mounted sensors, TPS has functions for detecting a fully-closed throttle and estimating intake air volume by the amount of throttle opening. Currently, we have conducted a study on transferring TPS functions into the MPS (manifold pressure sensor) in order to eliminate the TPS. Here we report on detecting a fully-closed throttle for achieving fuel cut control (FCC) and idle speed control (ISC) in fuel injection systems. We contrived a means for fully-closed throttle detection during ISC and controlling changes in the bypass opening during FCC in order to accurately judge each fully-closed throttle state via the manifold pressure. A factor in causing fluctuations in manifold pressure in a fully-closed throttle state are changes in the engine RPM (also referred to as engine speed) and changes in the degree of opening of the bypass (hereafter simply bypass opening).

This SAE Aerospace Information Report (AIR) has been prepared to provide information regarding options for optical control of fluid power actuation devices. It is not intended to establish standards for optical fluid power control, but rather is intended to provide a baseline or foundation from which standards can be developed. It presents and discusses approaches for command and communication with the actuation device via electro-optic means. The development of standards will require industry wide participation and cooperation to ensure interface commonality, reliability, and early reduction to practice. To facilitate such participation, this document provides potential users of the technology a balanced consensus on its present state of development, the prospects for demonstration of production readiness, and a discussion of problem areas within this technology. The intent is to inform the user/designer of the options available for interfacing photonics (optics) to hydraulic power control actuators used in aerospace applications.

Most of the Trimmable Horizontal Stabilizer Actuators (THSA) feature a dual structural load path, the primary load path being loaded, the secondary load path being normally unloaded, or both load paths sharing in parallel the Horizontal Stabilizer load. This document describes existing methods for detecting rupture or disconnection of loaded load paths as an overview for those specifying or designing Horizontal Stabilizer Trim Actuators in order to compare existing solutions as reference for implementation in new aircraft programs.
