In an electronic fuel injection system, the ECU calculates the optimum fuel injection volume for the current engine condition based on data from a wide range of sensor, and it injects this volume of fuel into the intake manifold at the optimum timing.
In MPFI-Electronic Control System, the sensors that monitor intake air temperature, the oxygen, the water temperature, the starter signal and the throttle position send signals to the ECU.
Which of the following is/are the advantages of using a control chart for inspection? (i) A control chart indicates whether the process is in control or out of control. (ii) A control chart determines process variability. (iii) A control chart ensures product quality. (iv) Scrap or percentage reduction can be reduced by taking the necessary actions in time against the warnings indicated by control charts. (v) Control charts build up the reputation of the organization through customer’s satisfaction. (vi) The control chart can detect the unusual variations taking place in a process.
Consider a control unit generating the control signals. These control signals are divided into five mutually exclusive groups as shown below: Groups  G1  G1  G1  G1  G1 Control  Signals   3  7  10  12  2 How many bits are saved using the Vertical Micro-programmed instead of Horizontal Micro-programmed control unit?
In the question given below,three paragraphs are given, which arejumbled. Find the correct sequence ofthese paragraphs so that they form ameaningful passage.
A. Climate change is warming the ocean,but its warming land faster and thatsreally bad news for air quality all overthe world, says a new University ofCalifornia, Riverside study. The study,published February 4 in Nature ClimateChange, shows that the contrast inwarming between the continents andsea, called the land-sea warmingcontrast, drives an increasedconcentration of aerosols in theatmosphere that cause airpollution. Aerosols affect the climatesystem, including disturbances to thewater cycle, as well as human health.They also cause smog and other kinds ofair pollution that can lead to healthproblems for people, animals, andplants.
B. To determine this, the researchersran simulations of climate change undertwo scenarios. The first assumed abusiness-as-usual warming model, inwhich warming proceeds at a constant,upward rate. The second model probeda scenario in which the land warmed lessthan expected. In the business-as-usualscenario, enhanced land warmingincreased continental aridity and,subsequently, the concentration ofaerosols that leads to more air pollution.
C. A robust response to an increase ingreenhouse gases is that the land isgoing to warm faster than the ocean.This enhanced land warming is alsoassociated with increased continental
aridity. The increase in aridity leads todecreased low cloud cover and less rain,which is the main way that aerosols areremoved from the atmosphere.
Consider the following regarding land revenue system: This system of land revenue was instituted in the late 18th century by Sir Thomas Munro, Governor of Madras in 1820. This was practised in the Madras and Bombay areas, as well as Assam and Coorg provinces. In this system, the peasants or cultivators were regarded as the owners of the land. They had ownership rights, could sell, mortgage or gift the land. The taxes were directly collected by the government from the peasants. Above are features of which of the following land system?
A government official said, “Currently, the traffic signals installed along the roads have a fixed signal timer but with the Japanese technology, signals will automatically change according to the number of vehicles along the road.” Which of the following could be the reason for the statement? I: The installation of smart signals will reduce the waiting time at signals and junctions. II: The installation of smart signals will solve the traffic woes in the city. III: The technology will be an integrated traffic management center that will ease congestion in the city.
In MPFI-Fuel system, the throttle receives signals from the ECU and inject the fuel into the intake manifold.
Consider the following statements regarding electronic voltmeter. 1) The detection of low-level signals is not possible using the electronic voltmeter 2) MOSFET is used at the input of the electronic voltmeter 3) Vacuum tube voltmeters (VTVM) consumes more power as compared to any non-electronic voltmeter.
