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

The Holy Grail Product with Horrible Packaging
Style: Cream, Size: 3.4 Fl Oz (Pack of 1)
This is a great nighttime routine product. The product itself? Fantastic, no complaints. There’s no dryness, skin feels silky, and it’s moisturizing but with no oiliness or residue. It has never irritated my skin, and I’ve never had to use a moisturizer on top of it. It’s also incredibly lightweight and it absorbs quickly. My one complaint? The container. In theory, I love the concept of a little button-pump bottle, but after a week or so, the product doesn’t reach the pump. If you buy this, just be aware to NOT THROW IT OUT just because it’s not coming out when you pump the container. You’re going to have to unscrew the lid (particularly with the bigger size) and then bam - you’ve got like two more months worth of product. I mean truly, like only a THIRD of the product can be dispensed the intended way, and the rest you’ve gotta unscrew and dip your fingers in. Which totally defeats the purpose. Great product, DUMB packaging.

See the pics!
Style: Cream, Size: 1.7 Fl Oz (Pack of 1), Style: Cream, Size: 1.7 Fl Oz (Pack of 1)
This stuff is incredible! I wish I had taken pics of my whole face but didnt think to. I noticed recently my cheeks looking smoother and significant improvement on the size of my pores so i went back to the pic I saved and it confirmed it's the result of using this cream. I have been using this for 3 months now. I don't think I've used half of it yet either. I apply it 6x a week at night. I do apply moisturizer after it dries as it doesnt provide enough moisture on my Tzone (which i do with any product). I absolutely love the dispenser on it and it is fragrance free. It's cruelty free as well. I highly recommend!!!! Would make a great gift too. For reference, I'm in my mid 30s, have sensitive oily skin with some dryness on my Tzone. I do not use any other anti-aging products. See the before and after pics! I will update.

Works well, very pleased
Style: Cream, Size: 1.7 Fl Oz (Pack of 1)
I had forgotten how well the three additives work together to make the complexion firmer, brighter and clearer. By making it a generic product., the quality is still all there, except the price is so much lower than the name brands with the same formula.

Poor/deceptive packaging
Style: Cream, Size: 1.7 Fl Oz (Pack of 1), Style: Cream, Size: 1.7 Fl Oz (Pack of 1)
I initially thought I was getting my money’s worth when I purchased this face cream, it seemed like a pretty generous amount for the price. That is, until product stopped coming out from the pump. I thought, okay whatever, I’ll just unscrew the top and get it with my fingers. That’s when I realized that not only is the pump setup stupidly ineffective, as it doesn’t actually reach the majority of the product (it only gets the product directly in the middle, all of the cream on the outside perimeter you’ll either have to get with your hands or move into the center). But the container only has like 1/3 of its volume’s worth of product. The other 2/3 of the container is just empty space. I can’t speak on the effectiveness of the cream itself, I honestly didn’t see any changes in my skin after 3-4 months of use. It was moisturizing enough. If anything, there were times I felt more prone to breakouts. But I would not recommend this product just simply on how deceptive the container is, making you feel like you’re getting a lot more product than you really are.

Great for men and anti-aging
Style: Cream, Size: 1.7 Fl Oz (Pack of 1)
I love this product. I use it every night as part of my face cleaning routine. After a face scrub and pat dry i use this moisturizer to lock in moisture. It has seriously been effective and it is very compatible with my skin. It feels pure and clean and has no scent. Great for men.
