Salah satu cara untuk mencegah terjadinya mesin berputar terus menerus setelah ignition switch (kunci kontak) diputar ke posisi OFF yaitu menghentikan supply bensin ke carburetor dengan menggunakan …
- A.
Throttle valve
- B.
Solenoid valve
- C.
Economizer jet
- D.
Choke
- E.
IMAS
Correct Answer
B. Solenoid valveExplanation
To prevent the engine from continuously running after the ignition switch is turned off, a solenoid valve is used to stop the supply of fuel to the carburetor. The solenoid valve acts as a shut-off valve, cutting off the flow of fuel when the ignition is switched off. This prevents the engine from receiving fuel and thus stops it from running. The other options listed, such as throttle valve, economizer jet, choke, and IMAS, do not directly relate to stopping the fuel supply and preventing the engine from running after the ignition switch is turned off.Rate this question:

Saat kecepatan stationer, campuran bahan bakar keluar dari karburator ke ruang bakar melalui...
- A.
Idle port
- B.
Main jet
- C.
Slow port
- D.
Main nozel
- E.
Air bleeder
Correct Answer
A. Idle portExplanation
At idle speed, the fuel mixture is delivered from the carburetor to the combustion chamber through the idle port. The idle port is a small passage that allows a small amount of fuel to flow into the engine when the throttle is closed. This ensures that the engine can continue to run smoothly at low speeds without stalling. The other options, such as the main jet, slow port, main nozzle, and air bleeder, are not relevant to the idle speed operation of the carburetor.Rate this question:

Pada saat mesin masih dingin, campuran bensin dan udara menjadi kurus sehingga mesin sukar hidup maka diperlukan suatu system yang dapat membuat campuran tersebut menjadi kaya (1 : 1) yaitu …
- A.
Power Sistem
- B.
Acceleration sistem
- C.
Choke Sistem
- D.
Idle sistem
- E.
Speed sistem
Correct Answer
C. Choke SistemExplanation
When the engine is still cold, the fuel and air mixture becomes lean, making it difficult for the engine to start. Therefore, a system is needed to make the mixture rich (1:1), which is the choke system. The choke system restricts the flow of air into the engine, creating a richer fuel mixture, which helps in starting the engine smoothly.Rate this question:

Untuk menjamin perbandingan bahan bakar dan udara (air-fuel ratio) ke mesin dengan penginjeksian bahan bakar yang bekerja secara kelistrikan sesuai dengan kondisi pengendaraan merupakan fungsi dari …
- A.
Carburator system
- B.
Acceleration System
- C.
Choke System
- D.
EFI System
- E.
Power System
- F.
Power System
Correct Answer
D. EFI SystemExplanation
The EFI system is responsible for ensuring the correct air-fuel ratio is delivered to the engine based on the driving conditions. It achieves this by electronically controlling the fuel injection process. Unlike a carburetor system, which relies on mechanical means to mix the fuel and air, the EFI system can precisely adjust the fuel injection based on factors such as engine load, temperature, and altitude. This allows for more efficient combustion and improved fuel economy. The other options listed, such as the acceleration system, choke system, and power system, do not directly relate to regulating the air-fuel ratio.Rate this question:

Correct Answer
A. Main jetExplanation
The main jet is responsible for controlling the amount of fuel that is delivered by the primary high-speed system. It regulates the fuel flow to ensure the engine receives the correct mixture of air and fuel for optimal performance. By adjusting the size of the main jet, the fuel flow can be increased or decreased, allowing for fine-tuning of the engine's fuel consumption and power output.Rate this question:

Ciri utama sistem injeksi bahan bakar kontrol elektronik (EFI) tipe ”L” adalah menggunakan ...
- A.
Air Valve Sensor
- B.
Oxygen sensor
- C.
Air Flow Meter
- D.
Throttle position Sensor
- E.
Manifold absolute pressure
Correct Answer
C. Air Flow MeterExplanation
The main characteristic of electronic fuel injection (EFI) system type "L" is the use of an air flow meter. This component measures the amount of air entering the engine, which is essential for determining the correct amount of fuel to be injected. By accurately measuring the air flow, the EFI system can ensure optimal fuel-air mixture for efficient combustion and improved engine performance.Rate this question:

Berfungsi mencegah goncangan bensin pada kondisi jalan yang tidak rata pada tangki adalah….
- A.
Separator
- B.
Fuel gauge sender unit
- C.
Drain plug
- D.
Fuel inlet tub
- E.
Baut klem
Correct Answer
A. SeparatorExplanation
A separator is a device that is used to separate different components or substances from each other. In the context of the given question, a separator is used to prevent fuel from sloshing around inside the tank when driving on uneven roads. This helps to stabilize the fuel level and prevent any potential damage or disruption to the fuel gauge sender unit, which is responsible for measuring the amount of fuel in the tank.Rate this question:
