The difference is one has 8, and the other has 16.
Had you asked why, the reply might have been different.
A d16z6 has 16 valves 8 intake and 8 exhaust valves.
16.
Any two numbers that have a distance of 16 between them, such as 0 and 16, or -16 and 0, or -8 and 8, or 6 and 22.
The main difference between oxygen-16 and oxygen-17 is their atomic mass. Oxygen-16 has 8 protons and 8 neutrons, while oxygen-17 has 8 protons and 9 neutrons. This difference in neutron number results in oxygen-17 being slightly heavier than oxygen-16.
Means it has 8 valves. Some have 16.
It is exactly what it says. The number of valves the engine has per cylinder. If you have 16 valves on an 8 cylinder engine, you have 2 valves per cylinder.
8 intake and 8 exhaust for a total of 16
The differences between the numbers is decreasing by 8 each time. Therefore, since the difference between 48 and 32 is 16, the difference between the next two numbers will be 16 - 8 = 8. Therefore, the next number in the sequence is equal to 32 - 8 = 24.
8 or 16 depending on engine size.
The answer to the division is a number (8) that can be added to itself to make 16. The answer to the square root is a number (-4 or +4) that can be multiplied by itself to make 16.
The GCF of 6, 8, and 16 is 2. The GCF can be no greater than the smallest difference between the numbers (in this case 8-6=2).
The Vauxhall Z16XE engine is a 16-valve engine. It features a double overhead camshaft (DOHC) design, which allows for four valves per cylinder, totaling 16 valves for the four-cylinder engine. This design enhances performance and efficiency compared to an 8-valve configuration.
