Gasoline Engine Model Four Stroke Single Cylinder Physical Experimental Equipment

Features:


.The gasoline engine model is designed according to the height of the object. It can clearly and intuitively explain the basic working principle of the four-stroke single-cylinder gasoline engine and the main structure of the common single-cylinder gasoline engine. It is suitable for teaching demonstration.

.Construction: The front side of the instrument is a section cut along the longitudinal axis of the cylinder, and the cylindrical cavity in the middle is a cylinder. On both sides of the cylinder is a section of the cooling water jacket. The piston moves up and down in the cylinder, and the lines on the piston represent the piston ring and the oil ring. The square cavity below the cylinder is the crankcase. The front part of the box is the crankshaft. It is connected to the piston through the connecting rod. The rear one is the camshaft. There are two cams with different positions on the top. The push rod is pushed up and down in turn and passed. The rocker arm controls the intake valve at the top of the cylinder and the opening and closing of the exhaust valve. In the middle of the top of the cylinder is a spark plug. The left side of the instrument is the flywheel, the right side has the curved wheel timing gear, the camshaft timing gear, the gear ratio is 1:2. The compression ratio of a gasoline engine is generally 5-8, so when the piston rises to the top dead center, the top of the cylinder is proportionally left with a certain gap. The instrument is equipped with a light display device, and the lights will flash in sequence when the instrument is running.

.How to Use: Connect the two terminals to the 1.5-2V power supply (or install the No. 5 dry battery into the battery clip on the bottom plate), close the switch, adjust the piston to the top dead center, and then slowly rotate in the direction of the arrow shown on the flywheel. The flywheel, respectively, describes the piston, intake valve, exhaust valve, ignition and other actions in the four strokes to clarify the basic working principle of the gasoline engine. Observe how the linear reciprocating motion of the piston is converted into the rotary motion of the flywheel, and how to control the push rod, the rocker arm and the air valve to move up and down when the camshaft rotates. The flashing of the electric bead on the top of the cylinder indicates the ignition (the instrument has an advance angle of ignition, so the ignition Is done when the compression stroke is not completely finished)

.Note: This model is generally shipped after adjustment, all components have been assembled, do not arbitrarily move or disassemble. Operate the instrument according to the instructions for use. Please keep it after use and pay attention to the cleaning and maintenance of the instrument for longer use..Suitable for people over 14 years old

This sticks to my Chrysler Pacifica!
I bought a new-to-me Chrysler Pacifica and of course wanted a phone holder or two for when my husband and I are travelling. I absolutely adore the car, but I've never had so much trouble finding a phone holder that would stick to the dash, no matter how thoroughly I cleaned it with alcohol! Finally found this one, but it only sticks if you do NOT activate the suction part. That pulls the sticky part off the dash. And it's not very attractive on top of the dash. I'm more concerned with function than appearance so I'm happy with it, and it works great. The phone stays put and stays charged, which is all I ask.

Imperfect, sometimes charging is unreliable, clamp needs power to work and annoyingly not auto
The build quality is great for the price. Like iOttie. The tech advancement is cool but it doesn't work very well which is a disappointment. It doesn't charge my phone very fast, because my phone is limited to 15 watt wireless charging, but it's great for preventing battery loss while using GPS. The button to manually clamp and unclamp are a little too hard to press, it flexes the whole holder, so you need to press with your whole hand supporting the holder. Sometimes my phone disconnects and reconnects randomly to this charger multiple times. Not sure if it's the charger or phone but that stinks . (I'm using an Anker 50w USB adapter for this wireless charger) The clamping is motorized which is cool, but it's honestly less reliable than a spring loaded clamp because it doesn't always auto clamp the phone. When this clamp is working properly it is great as it auto clamps onto a phone it's charging. But the issue is it doesn't always clamp. It sometimes thinks it's clamped, when it's not, so you have to press the manual activation button twice so the phone will be locked in place. It's hard to know when you need to press just once or twice. (The reason you press the button twice is if it thinks it's closed when it's actually open. Then you press first to "open" the clamp, even though it's already open, then press again to close it. But if it knows the correct clamp position already, and just refuses to auto clamp, you only press the button once. If you press twice, you will end up cancelling the clamp. It feels random and unpredictable what the correct action is) The clamping requires power which is another disadvantage to spring loaded hand clamps. But unclamping works without power due to a backup battery. (Powered clamping is still better than those manual squeeze clamps, which are finicky to get a strong enough clamp on the phone) I'm not sure how safe the battery is in a super hot car, like Florida heat. It seems fine for Pa heat.
