What is the structure of a fuel gauge?

1 Answers

The fuel gauge consists of a metal rod and a float, with the float typically made of foam plastic. The end of the metal rod is connected to a variable resistor. A resistor is a device used to impede the flow of electric current. The greater the resistance, the smaller the current that passes through. The fuel gauge is a very simple device. The current flowing from the sender passes through a resistor, which may be wrapped around or located near a bimetallic strip. The bimetallic strip is connected to the pointer of the fuel gauge via a linkage. When the resistance increases, the current through the heating coil decreases, causing the bimetallic strip to cool down. As the strip cools, it straightens, moving the fuel gauge pointer from full to empty. The function of the automotive fuel gauge is quite advanced, capable of displaying the fuel level in the tank in real-time, accurately informing the owner about fuel consumption and remaining tank capacity. The fuel gauge can indicate whether refueling is needed and how much distance can be traveled after refueling. Essentially, the fuel gauge acts as a warning light for the vehicle's life. It is an indicator on the engine that displays fuel level, either via a pointer or digital readout. Automotive fuel gauges are mainly divided into two types: digital display fuel gauges and pointer display fuel gauges.

What is the motor power of the Changan Benben EV?

The motor power of the Changan Benben EV is 30kW and 55kW, with two different powertrain models: the EC260 and the EC360. The Changan Benben EV is a single-motor vehicle, and its motor is front-mounted, making it front-wheel drive. For microcars, there is insufficient space at the rear to install complex independent suspensions, so microcars typically use a torsion beam for the rear suspension. The torsion beam suspension is a common type of non-independent suspension, known for its simple structure, compact size, and minimal space requirements.

What transmission is used in the Changan Eado manual version?

Changan Eado manual version uses a 5-speed manual transmission. The following are the relevant details: Features of the 5-speed manual transmission: The five-speed transmission adopts a two-shaft layout, eliminating the conventional intermediate shaft, and is a longitudinally mounted front-drive transmission integrated with the main drive bevel gear and differential. It receives engine power through the input shaft, changes speed via various gear sets, and utilizes the output shaft, main reduction gear, and differential gear mechanism to drive the front wheels. Introduction to Changan Eado: The Changan Eado is a compact sedan launched by Changan Automobile, available in two powertrain options: a 1.6L engine and a 1.4T turbocharged engine. The 1.6L engine delivers a maximum power of 128 horsepower, while the 1.4T engine produces a maximum power of 158 horsepower. In terms of the transmission system, the 1.6L model is paired with either a 5-speed manual transmission or a 6-speed automatic transmission, and the 1.4T model is matched with a 7-speed dual-clutch transmission.

What is the fault when the EPS light is on in the Changan Honor?

When the EPS light is on in the Changan Honor, it indicates a fault in the power steering system, and the steering wheel will become heavier. The power steering systems in automobiles include: electric power steering system, electro-hydraulic power steering system, and mechanical hydraulic power steering system. The electric power steering system does not have hydraulic mechanisms; this system relies on an electric motor to provide steering assistance. The electro-hydraulic power steering system is actually developed based on the mechanical hydraulic power steering system. Both of these power steering systems have hydraulic mechanisms and require the use of power steering fluid. The electro-hydraulic power steering system simply adds some electronic systems to the mechanical hydraulic power steering system.

How many cylinders does the Changan Benben have?

Changan Benben is equipped with a four-cylinder engine. The entire Changan Benben series uses a 1.4-liter naturally aspirated engine with a rotation speed of 6000 rpm. This engine is equipped with VVT technology and multi-point electronic fuel injection technology, and uses an aluminum alloy cylinder head and block. The engine is paired with either a 5-speed manual transmission or a 5-speed AMT transmission. The front suspension of the Changan Benben uses a MacPherson independent suspension, while the rear suspension uses a torsion beam non-independent suspension. Most microcars use torsion beam rear suspensions due to their simple structure, small size, and minimal space occupation. This type of suspension is very suitable for microcars, as it helps to expand the rear seating space and trunk space.

What is the best engine oil for Changan Lingxuan?

Changan Lingxuan can use synthetic or mineral engine oil. This model offers two powertrain options: a 1.6L naturally aspirated engine and a 1.5T turbocharged engine. For models with naturally aspirated engines, mineral or semi-synthetic oil can be used; for turbocharged engine models, semi-synthetic or full-synthetic oil is recommended. The Changan Lingxuan features a three-bar horizontal grille combined with dynamic headlight and fog light designs, presenting an overall stable appearance. The vehicle dimensions are 4730mm in length, 1795mm in width, 1730mm in height, with a wheelbase of 2760mm.

Does Installing an Engine Guard Plate Affect Heat Dissipation in Cars?

Engine guard plates do have an impact on vehicle heat dissipation, but the effect is minimal. The specific reasons are as follows: 1. The heat dissipation performance of an engine is primarily reflected in the front grille, engine compartment design, water pipes, and radiator design, with only a small portion dissipating through the chassis. 2. Engine guard plates are custom-designed protective devices for various vehicle models. Their primary purpose is to prevent mud from encasing the engine, which could lead to poor heat dissipation, and secondly to protect the engine from damage caused by impacts from uneven road surfaces during driving. Through these designs, they aim to extend the engine's service life and avoid vehicle breakdowns due to external factors causing engine damage during travel.
