Computer engineers solve problems in hardware, software, systems, and networks so things like your laptop or big airplanes work properly. Computer engineers make current devices we use for work and entertainment faster, smaller, cheaper, smarter, and safer.
Computer engineering is engineering of software and hardware at the level of computer (computation). that's how I look at computer science. By the way, you can be a pure computer scientist, and just do research, and decide to isolate yourself from the engineers.
